Shah, Janvi Pankaj. "Resilient geotechnical asset management." Thesis, University of Birmingham, 2016. http://etheses.bham.ac.uk//id/eprint/6644/.
Full textAbstract:
There is overwhelming evidence that the development of new, technically sound, engineered and fit-for-purpose critical physical infrastructure is vital for economic growth and stability. With many countries targeting significant levels of capital investment in energy, transport, communications, flood management and water and waste water infrastructure, there is a vital need for asset management frameworks that can provide both robust and resilient asset support. Currently, asset management tools focus predominantly on data management, deterioration modelling, condition assessment, risk, as well as economic factors (such as whole-life costing and developing investment plans). Some also consider the vulnerabilities of a network to climate change and extreme weather events such as flooding. However, rather than taking a long term view, asset management strategies are often short term, typically five years or less. What is needed is a long-term approach, which will ensure assets are safe, secure and resilient to what the future may hold in 20, or even 50 years’ time. The thesis describes the development of a ‘Resilience Assessment Framework’ which provides a platform to appraise resilience of geotechnical assets in the planning stage of asset management by considering how geotechnical assets (specifically for transport infrastructure) designed and built today will perform in the light of socio-economic, environmental, political, technological changes and shock events in the future. This framework intends to assist in strategic level decision-making by enabling long term planning and management of geotechnical assets and help future proof transport infrastructure. The proposed framework is validated using two real case studies to demonstrate its use and applicability in the field of geotechnical asset management.

Full textAbstract:
Many problems in geotechnology are concerned with the response of earth materials to cyclic loads. These loads are either generated by forces of nature such as sea waves, currents, winds, and earthquakes or as a consequence of engineering operations such as blasting, pile driving and rotating machines. For most design purposes related to static loads it is logical to use as a design basis either the elastic range where no plastic deformation occurs or the plastic range, in which large plastic deformation can occur. However, when cyclic loading is involved few design methods are available since a pattern for the response of the body to cyclic loads is not well known. When a body is subjected to cyclic loading some modes of adaptation or non adaptation can occur as a response to the loads such as elastic shakedown, alternating plasticity and ratchetting. Despite its extensive use in structural problems very few applications of the shakedown approach to soil masses can be found in literature. Therefore the present work aims to extend the elastic shakedown concepts to geotechnical problems. Initially the shakedown concepts are introduced, its theorems and their importance for geomechanical problems are highlighted. Later the use of Melan's static shakedown theorem for the present study is shown. Shakedown analyses of plane stress and plane strain problems are presented. In this study the shakedown formulation is based on the concept of a residual stress field obtained by means of a numerical formulation using a visco-plastic algorithm. Two numerical codes linked with a mesh generator were implemented as tools for the treatment of the shakedown problems. Numerical examples and applications are shown to illustrate the usefulness of the present approach.

Full textAbstract:
Chalk putties are common in Southern England, occurring naturally and as a result of earthworks in intact chalk. The ease and readiness with which intact chalk breaks down into putty makes establishing a good geotechnical profile of the material necessary. A review of literature indicates that previous laboratory studies on chalk putties are limited, and that testing of the material has proven difficult using standard procedures. This study initially quantifies index parameters such as Atterberg limits, thixotropy and particle size distribution before considering susceptibility to age-related strength gains and shear strength-strain dependency so that subsequent shear test data can be normalised. Contrary to literature, age-related strength gains were found to be minor, whilst shear strength-strain dependencies were found to be significant. Large strain tests in ring shear apparatus (following recommended test procedures) found non linearity in the drained shear failure envelopes, with effective friction angles (Ø') increasing with strain. This non linearity is explained by sample grading evolution. Using these findings the study develops new preparation and testing methodologies to create ‘identical soils’ of known stress history. Testing in a computer governed stress path cell (using ‘Triax’ software) found that chalk putty behaves as a contractive material, ‘wet’ of its critical state, exhibiting failure by liquefaction for mean effective stresses (p') lower than 200kPa. Pre and post yield permeability values in the range 2.5-13 x 10-9m/s were recorded with state parameters indicating a constant a pre shear p' of between 0 and 400kPa.

Full textAbstract:
Geotechnical engineering has a crucial role to play in enhancing sustainability due to its pivotal role in the construction process where potentially impacts are highest. Currently, there is a lack of methodologies for assessing geotechnical projects that truly encompass the three core pillars of sustainability. A robust system is required which offers an holistic approach that is both flexible and easily understood, whilst not being biased towards rewards or is prohibitively costly. In addition, ‘tool fatigue’, whereby a system is generated but never used, must be avoided. After a detailed evaluation of the systems available, the SPeAR® framework was selected. Following detailed discussion with a variety of practitioners, the methodology was significantly adapted to make it applicable to geotechnical problems and ensure that geotechnical engineers can understand and use it with relatively ease. The new version, called ‘GeoSPeAR’ in this thesis, allows for greater communication between masterplanning and geotechnical engineering via their common base, thus avoiding a potential barrier to greater adoption of more sustainable practices through the construction cycle. Three case studies demonstrated the assessment of the ‘GeoSPeAR’ methodology. These showed the practical application of the system and how this effectively supports geotechnical engineers in embedding sustainability into projects.

Full textAbstract:
Mines have an inherent risk of geotechnical failure in both rock excavations and tailings storage facilities. Geotechnical failure occurs when there is a combination of exceptionally large forces acting on a structure and/or low material strength resulting in the structure not withstanding a designed service load. The excavation of rocks can cause unintended rock mass movements. If the movement is monitored promptly, accidents, loss of ore reserves and equipment, loss of lives, and closure of the mine can be prevented. Mining companies routinely use deformation monitoring to manage the geotechnical risk associated with the mining process. The aim of this dissertation is to review the geotechnical risk management process to optimize the geotechnical risk management analysis. In order to perform a proper analysis of slope instability, understanding the importance as well as the limitations of any monitoring system is crucial. Due to the potential threat associated with slope stability, it has become the top priority in all risk management programs to predict the time of slope failure. Datasets from monitoring systems are used to perform slope failure analysis. Innovations in slope monitoring equipment in the recent years have made it possible to scan a broad rock face in a short period with sub-millimetric accuracy. Instruments like Slope Stability Radars (SSR) provide the quantitative data that is commonly used to perform risk management analysis. However, it is challenging to find a method that can provide an accurate time of failure predictions. Many studies in the recent past have attempted to predict the time of slope failure using the Inverse Velocity (IV) method, and to analyze the probability of a failure with the fuzzy neural networks. Various method investigated in this dissertation include: Minimum Inverse Velocity (MIV), Maximum Velocity (MV), Log Velocity (LV), Log Inverse Velocity (LIV), Spline Regression (SR) and Machine Learning (ML). Based on the results of these studies, the ML method has the highest rate of success in predicting the time of slope failures. The predictions provided by the ML showed ~86% improvement in the results in comparison to the traditional IV method and ~72% improvement when compared with the MIV method. The MIV method also performed well with ~75% improvement in the results in comparison to the traditional IV method. Overall, both the new proposed methods, ML and MIV, outperformed the traditional inverse velocity technique used for predicting slope failure.

Full textAbstract:
This thesis presents the results of an investigation of factors which influence the geotechnical properties of frozen mine backfill (FMB). FMB has extensive application potential for mining in permafrost areas. The uniaxial compressive strength (UCS) of hardened backfill is often used to evaluate mine backfill stability. However, the deformation behaviour and stiffness of the FMB are also key design properties of interest. In this thesis, uniaxial compressive tests were conducted on FTB and FCPB samples. Information about the geotechnical properties of FMB is obtained. The effects of FMB mix components and vertical compression pressure on the geotechnical properties of FMB are discussed and summarized. An optimum total water content of 25%-35% is found in which the strength and the modulus of elasticity of the FTB are 1.4-3.2 MPa and 35-58 MPa, respectively. It is observed that a small amount (3-6%) of cement can significantly change the geotechnical properties of FTB.

Full textAbstract:
On January first 2011, the National Board of Housing, Building and Planning - Boverket, are adopting the European design rules of geotechnics. This will make the overall Swedish transition more definite. Geotechnical engineers and field-/laboratory technicians will have to conform their reporting routines to the new legal framework that the Eurocode suggests. The new standard will lead towards a better quality of the performed work, the reason being higher demands on the reports content and availability. It will also foster the free market, both nationally as well as internationally. The report system currently used will be replaced by a new system consisting of five different document types. The document types are: 1. Field Report 2. Test Report 3. Ground Investigation Report 4. Design Report 5. Tender Request Documentation Comparing the present system with the new, there is a certain extent of conformance in content. However, in terms of documentation, the new reporting model places higher demands on the geotechnical engineers and technicians. The reporting model will provoke a more elaborate and comprehensive communication between field-, laboratory- and desk units. The responsibilities of laboratory- and field technicians will increase in terms of quality and documentation in field investigation. Not only will the increased requirements in reporting affect the routines of field- and laboratory staff. In order to receive sufficiently exhaustive material that meets the requirements of the Eurocode, geotechnical engineers will have to be more precise in their informational inquiry. They have to support the technicians in distinguishing the additional information that has to be accounted for in the new document types. The Eurocode transition need not increase the turnaround times, and the design cost of geotechnical projects dramatically. But in order to maintain the current design costs, entrepreneurs in the industry have to adapt to the new game rules of European geotechnics.Den första januari 2011 blir den Svenska övergången till Eurocode inom Geoteknik mer definitiv i samband med att Boverket antar det nya regelverket. Geotekniska handläggare och fält-/labtekniker får i och med övergången ett nytt ramverk för rapportering och redovisning att arbeta efter. Den nya standarden kommer leda till en förbättrad kvalité på arbetet då kraven på redovisningens innehåll samt tillgänglighet ökar. Den kommer även befrämja den fria marknaden, både nationellt och internationellt. Det rapporteringssystem som i dagsläget används kommer ersättas av ett nytt som innefattar fem olika dokumenttyper. Dessa dokumenttyper är: 1. Underlagsrapport 2. Försöksrapport 3. Markteknisk undersökningsrapport 4. Projekterings PM 5. Förfrågningsunderlag. Innehållet i de nya rapporttyperna knyter i många avseenden an till innehållet i de som används idag. Den nya rapporteringsmodellen ställer dock ur ett dokumenteringsperspektiv högre krav på handläggare och tekniker. Modellen kommer provocera fram en mer detaljerad och innehållsrik kommunikation mellan fält, laboratorium och kontor. Tanken är att personer som inte varit inblandade i ett projekts tidigare skeden skall kunna ta till sig alla förutsättningar med hjälp av de nya dokumenten. Mer ansvar kommer läggas på lab- /fälttekniker vad avser kvalitet och dokumentation i projektens undersökningsfas. För att man från fält och lab. skall kunna ta fram rätt underlag till fortsatt projektering måste handläggare tydligare precisera vilken typ av information, utöver den traditionella, som måste finnas med i resultatredovisningen. För att övergången inte i för stor utsträckning skall påverka handläggningstid och projekteringskostnad måste företagen anpassa sin verksamhet efter de nya spelregler som Eurocode medför.

Smith, James Seymour. "Scaled geotechnical centrifuge modelling of gelifluction." Thesis, Cardiff University, 2004. http://orca.cf.ac.uk/54676/.
Full textAbstract:
This thesis describes the laboratory modelling of gelifluction processes using the geotechnical centrifuge technique. Thirteen 1/10 scale planar slope models were frozen from the surface downwards on the laboratory floor and thawed, also from the surface downwards, under gravitational acceleration of 10 gravities (approximately 98.1 ms'2). A natural sandy silt soil from Quaternary periglacial slope deposits collected in SW England formed the base test material and slope models at gradients 4, 8, 12 and 16 were constructed using this soil. 10% and 20% by weight increments of glaciolacustrine silt and Kaolinite clay were added to the natural soil and a series of slope models were constructed at gradients of 4, 8, and 12 using these soils. Each slope model was subjected to four cycles of freezing and thawing except for the four slope models that underwent rapid slope failure. During thaw, soil temperatures and pore water pressures were recorded continuously, together with soil thaw settlement and surface displacement. Following each experiment, models were sectioned to observe displacement columns that showed the profiles of soil movement and allowed volumetric displacements to be calculated. It was shown that thaw settlement and slope gradient strongly affected the rate of surface movement and the subsurface profile of movement. Increasing slope gradient generated greater amounts of subsurface and surface movement as a function of increased gravitational shear stress. Thawing ice lenses inclined parallel to the slope gradient provided localised zones of microshearing in response to localised low frictional resistance. Rates of movement increased between the 4 and 8 models, but a greater increase occurred between the 8 and 12 models. A slope failure was initiated within the 16 slope model. Rates of gelifluction were dominantly influenced by increasing silt content impacting upon the distribution of segregated ice and the reduction of frictional shear strength. Increasing silt content generated high positive porewater pressures commonly in excess of hydrostatic and consequently greater amounts of pre-failure strain. A clear behavioural threshold was identified between the 10% and 20% silt soils, with far greater gelifluction in the latter than the former. Increasing clay content had a less pronounced impact upon rates of gelifluction when compared to increasing silt due to cohesion. Rates of movement increased between the 10% and 20% clay in response to lower shear strength. A sawtooth style of pore pressure response caused by water escape events within the 20% clay prevented maximum potential pressures being achieved and possibly impacted upon the overall rate of gelifluction. A successful simulation of both landsliding and slow mass wasting processes was undertaken and future applications for the technique have been outlined.

Meanwhile in the last years it can be observed the increase of the use these equipaments based on electrical principle like resistance extensometers and electrolevels that can be coupled to efficient system data aquisition. So there is need of the use of techique more precise and comprehensive for monitoring actual behaviour of geotechincal work so the big distance that there is between refinement, sofistication and versatility of computacional and numeric methods in relationship quality and representative information from observation programs in the geotechincal engineering, can be shortened. The main purpose of this research is to verify the aplication of electrolvel gauges in geothecnical instrumentation program and to develop specific procedure of assembly, calibration, installation and interpretation. This instrumentation technique in spite of being internationally established is still of restricted use in our country. Results obtained in two large concrete face rockfill dams (Xingo and TSQ-1) are presented.

The Department of Energy (DOE) has recently announced that the Superconducting Super Collider (SSC) will soon be built somewhere in the United States. Preliminary geophysical studies indicate that the Sierrita site 35 miles southwest of Tucson has geological conditions that would facilitate construction of the SSC. The Maricopa site southwest of Phoenix is also one of the two potential sites in Arizona. However, several additional geotechnical investigations were required to convincingly demonstrate the suitability of these two locations. The present research program identified the geotechnical properties of the soils at the two sites through various levels of laboratory and field testing. The significance of these results are discussed and recommendations are given.

Full textAbstract:
In industry, particulate waste materials may be disposed of by mixing with water and then pumping to a void where the particles will sediment out and the excess water will be decanted. This waste disposal method can result in very large volumes of material which are described as being 'hydraulically placed fills'. The waste material often consists of very fine particles, which can have a wide variety of composition, shape and size. The final sediments may have a very high moisture content and be difficult materials for sampling and testing and for construction purposes. The hydraulically placed fills covered in this study, pulverized fuel ash (PFA) and I ' fluorspar tailings, consist mainly of particulate material in the fine' sand to silt range. The study focuses on the compressibility and shear strength characteristics of these materials and was based on laboratory testing of reconstituted specimens. A water pluviation technique was used for specimen preparation which simulates in-situ conditions. This resulted in very loose samples (e-I.60) for one dimensional (I-D) consolidation and triaxial tests. The original materiafs and mixes of varying fines content were tested. The compressibility ofPFA alJd fluorspar mine'tailings was found to be similar to that of sands, with a unique first loading stage depen~ant on initial conditions, an elastic rebound on unloading and a normal compression line (NCL) at high stresses. Secondary compression was found to be linear with respect to the logarithm of time and significant for these types of deposits. The use of a fractal crushing compressibility equation was found to be suitable for estimating the coefficient ofcompressibility ofthe materials. Undrained and drained triaxial shear tests were performed on both materials. In the undrained tests, the specimens showed variable degrees of instability, defined as loss of shear strength after a peak value is reached. An initial state parameter (vo), based on the I-D NCL, is proposed as a practical and simple method for classifying the undrained behaviour of the materials. The critical state line, peak stress ratio and the stress ratio defining phase transformation (also known as quasi-steady state) were found to be parallel to NCL in e:log p' space The amount of fines affected these gradients with shallower slopes corresponding to smaller fines contents. No instability was observed on the drained tests. The use of Bolton's relative dilatancy index ~djusted for values of Q consistent with the crushing strength of the particles, gave a good correlation with the observed drained behaviour.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIORNos últimos anos, a aplicação da técnica de redes neurais tem sido difundida em diversas áreas do conhecimento, inclusive na engenharia civil. Em meados da década de 90, iniciaram-se no Brasil estudos no sentido de avaliar a eficiência desta técnica numérica na modelagem do comportamento de solos e na análise de problemas envolvendo engenharia geotécnica. Este trabalho é resultado de parte destes estudos, onde algumas das potencialidades do uso das redes neurais em geotecnia podem ser observadas. São apresentadas três aplicações diferentes de redes neurais feedforward em geotecnia, tendo sido treinadas com o algoritmo LM (Levenberg-Marquardt). A primeira aplicação diz respeito à simulação de resultados de provas de carga dinâmica, analisadas pelo método CAPWAP, através de redes neurais, sendo assim viabilizada a realização de uma pré- análise do comportamento da estaca ainda em campo, o que geralmente não acontece quando se trata da análise CAPWAP tradicional. A segunda aplicação relaciona-se com a análise do comportamento mecânico de dois tipos de solo bastante diferentes entre si: a areia de Ipanema e o solo residual gnáissico do Rio de Janeiro. Para tal, foram utilizados resultados de ensaios de cisalhamento direto, submersos e não submersos, e ensaios de compressão triaxial, drenados e não drenados. A terceira aplicação refere-se à simulação das características do subsolo do sítio da Usina Nuclear Angra 2, localizada no litoral do estado do Rio de Janeiro. As informações disponíveis eram advindas de boletins de sondagens do tipo SPT. Foram realizadas simulações envolvendo a disposição das camadas dos diferentes tipos de solo que poderiam existir no local, o nível de água subterrâneo, a resistência à penetração do solo e a topografia do terreno. Em todos os casos foram obtidos resultados bastante satisfatórios. Portanto, conclui-se que a técnica das redes neurais apresenta grande viabilidade na resolução de problemas geotécnicos de diferentes características, muitas vezes se mostrando tanto ou mais eficiente que as técnicas numéricas tradicionais.
During the last years, neural networks applications have been disseminated in many knowledge areas, including civil engineering. In the middle 90`s, a research work had been started in Brazil, in order to investigate the efficiency of neural networks in the analysis of soil behavior and problems involving geotechnical engineering. This thesis is the result of part of these studies, where some potentialities of neural networks technique are presented. Three different feedforward NNs applications in geotechnical engineering are presented. Levenberg- Marquardt algorithm was used for training. The first application is the simulation of results of dynamic pile tests, obtained from CAPWAP analysis, showing that it is possible to do a field pre-analysis of the pile behavior, which is still unpracticable when the traditional CAPWAP method is used. The second application is related to the study of two different soils behavior:sand from Ipanema and residual gnaissic soil from Rio de Janeiro. Results of submerged and non submerged direct shear tests and drained and undrained triaxial compression tests were used. The third application involves the simulation of subsoil characteristics of Angra 2 Nuclear Power Plant site. The available information came from SPT bulletins. Simulations involving several types of soil layers spatial distribution, water level position, penetration strength of soils and local topography were performed. The obtained results were very satisfactory. It can be concluded that the neural networks technique presents great applicability in resolution of geotechnical problems with different characteristics, showing an efficiency as good or even better than other traditional numerical techniques.
En los últimos anos, la aplicación de técnicas de redes neurales se ha difundido en diversas áreas del conocimento, incluso en la ingeniería civil. A mediados de la década de 90, se iniciaran en Brasil estudios para evaluar la eficiencia de esta técnica numérica em modelos de comportamiento de suelos y en el análisis de problemas de ingeniería geotécnica. Este trabajo es el resultado de parte de estos estudios, donde pueden ser obseravdas algunas de las potencialidades del uso de las redes neurales en geotecnia. Se presentan tres aplicaciones diferentes de redes neurales fedforward en geotecnia, entrenadas con el algoritmo LM (Levenberg Marquardt). La primera aplicación se refiere a la simulación de resultados de pruebas de carga dinámica, analizadas por el método CAPWAP, a través de redes neurales, realizando un pré análisis del comportamiento de la estaca en campo, lo que generalmente no sucede cuando se trata del análisis CAPWAP tradicional. La segunda aplicación se relaciona con el análisis del comportamiento mecánico de dos tipos de suelo bastante diferentes entre sí: la arena de Ipanema y el suelo residual gnáisico de Rio de Janeiro. Para esto, se uilizaron resultados de ensayos de cisallamiento directo, submersos y no submersos, y ensayos de compresión triaxial, drenados y no drenados. La tercera aplicación se refiere a la simulación de las características del subsuelo del sitio de la Planta Nuclear Angra 2, localizada en el litoral del estado del Rio de Janeiro. Las informaciones disponibles provenian de boletines del tipo SPT. Se realizaron simulaciones que involucraban la disposición de los diferentes tipos de suelo que podrían existir en el local, el nível de agua subterránea, la resistencia a la penetración del suelo y la topografia del terreno. En todos los casos fueron obtenidos resultados bastante satisfactorios. Por lo tanto, se concluye que la técnica de redes neurales presenta gran viabilidad en la resolución de problemas geotécnicos de diferentes características, muchas veces mostrándose tanto o más eficiente que las técnicas numéricas tradicionales.

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOO comportamento geotécnico da barragem de Curuá-Una, Pará, foi estudado devido à importância que a barragem representa para a Região Norte do Brasil. A usina hidrelétrica de Curuá-Una, inaugurada em 1977, está localizada na Amazônia, próxima à cidade de Santarém. O estudo englobou a avaliação das condições atuais de operação e a previsão de desempenho após uma possível elevação de 1,5m do nível do reservatório, com e sem alteamento simultâneo da crista da barragem. A elevação do nível do reservatório possibilitaria o aumento da potência útil da usina, beneficiando toda a região. Uma ampla campanha de ensaios geotécnicos foi realizada em amostras indeformadas dos materiais constituintes da barragem. As amostras de bloco foram extraídas dos taludes de jusante e montante, acima do nível freático. O programa experimental incluiu ensaios de caracterização, permeabilidade, adensamento, cisalhamento direto, e triaxiais, com diferentes condições de umidade. A pesquisa envolveu também a análise dos resultados da instrumentação de campo, composta por piezômetros instalados no corpo da barragem e na fundação de material arenoso. Uma surgência da linha freática foi identificada no talude de jusante, sugerindo um funcionamento inadequado do filtro vertical. As análises englobaram simulações numéricas da elevação do nível do reservatório e da cota da crista da barragem, com o objetivo de avaliar a deformabilidade do maciço. Foram também definidos os níveis de alerta referentes à segurança da barragem, com base em estudos de estabilidade realizados para diferentes condições de geometria e carregamento.
The geotechnical behavior of Curuá-Una dam, Pará, was studied due its importance to the North Region of Brazil. The power plant, in operation since 1977, is located in the Amazon forest, next to the city of Santarém. The study was comprised of the evaluation of current operation conditions of the dam and prediction of its performance after a possible rise of 1,5m of the level of the reservoir with and without simultaneous rise of the dam s crest. The rise of the reservoir would increase the power capacity of Curuá- Una plant, benefiting the entire region. A comprehensive program of geotechnical tests was carried out on undisturbed samples of the dam materials. Block samples were extracted from the upstream and downstream slopes of the dam. The experimental program included characterization tests, permeability, consolidation, direct shear and triaxial tests, with different saturation conditions. The research also included the analysis of field instrumentation results. The instrumentation included several piezometers, installed in the body of the dam and in the sandy foundation. A surgency of the freatic line was identified at the downstream slope, suggesting a malfunctioning of the vertical filter. The analyses included numerical simulations of different reservoir and crest levels, with objective to evaluate the deformability of the earth embankment. In addition, stability studies for different geometries and loading conditions were also carried out. Alert levels regarding the dam s stability were established.

Full textAbstract:
There is an urgent need to develop robust tools and policies for stability and hazard risk assessments in order to manage upland peat landslides in locations such as the British Isles where they have frequently occurred and caused harm to the environment. One of the particular difficulties is that reliable values of peat strength are difficult to obtain. The objectives of this research were to establish the nature of any relationships between the strength characteristics and the botanical, physical and chemical properties of the peat, and to determine whether palaeobotanical analyses of samples of the basal peat can provide a reliable indication of potential instability in upland blanket bogs. The research was carried out at the Straduff Townland (Co. Sligo), Slieve Anierin (Co. Leitrim) and Slieve Rushen (Co. Cavan) landslides, all located in northwest Ireland, from the margins of which monolith and core peat samples were collected. Standard and validated paleobotanical, chemical and geotechnical protocols, modified or refined where necessary to suit the nature of the peat, were used in the study. The triaxial, direct shear and tensile strength tests were conducted using experimental very low stress conditions in order to fully replicate in-situ conditions. The reliability of the measured strength parameters was examined by performing deterministic and probabilistic stability analyses of the failed slopes using industry-standard „limit equilibrium‟ software (SLOPE/W). The nature, extent and spatial distribution of the hydrocarbons unexpectedly found in the basal peats during the fieldwork were also investigated. This research found that blanket peat dominated by monocotyledons (with mainly E. vaginatum) is likely to be susceptible to failure because its „effective structural properties‟, specifically the high degree of humification and low fibre content of its basal peat, cause it to have very low strength and also therefore a very low bearing capacity. Furthermore, monocotyledons or its remains in peat have morphological, chemical, biological features that can promote bogflow-type failure. These may include for example (i) their parallel and elongated leaf veinations that promote flow, (ii) the genesis of hydrocarbons such as bitumen from their lignified tissues and (ii) being host to a hydrocarbon-producing aphid Colopha compressa. Laboratory measurements of undrained strength of the weak basal peats were consistently < 3 kPa, and deterministic stability analyses revealed that the value of the tensile strength can be used as an indicator of the undrained shear strength. A new classification (i.e. "the modified fibre content scheme") and a modified procedure for assessing upland peat failure for construction projects has been proposed based on peat fibre and humification characteristics and their apparent influences on peat strength. Deposits of hydrocarbons such as bitumens within the basal peat constitute a previously unrecognised factor that probably contributed to the occurrence of the studied landslides due to their hydrophobic properties.

Full textAbstract:
Recent years have seen the growing interest in the novel field of biogeotechnologies. Of particular interest to researchers has been the microbially induced calcium carbonate precipitation (MICP) for geotechnical (stabilisation of soils) and geoenvironmental (immobilisation of contaminants) applications. The MICP process results in the formation of a brittle monolith from sand cemented by the microbial calcium carbonate which will, however, be subjected to chemical and physical deterioration over time. This will bring the need for repair of the earth structure which can be highly difficult and costly. This study investigates the possibility of incorporating a self-healing mechanism in the MICP that will allow the initially formed monolith to be healed after damage. MICP via a spore-forming, ureolytic organism, Sporosarcina ureae, was evaluated for its self-healing potential. The most commonly used organism in biocementation, namely Sporosarcina pasteurii, was found to not form spores. Experiments in aqueous solution showed that encapsulated (in calcium carbonate) sporulated bacteria can survive harsh conditions, starvation for periods of 6 months (while encapsulated within the mineral) and be able to germinate once exposed from the mineral matrix with availability of nutrients. The revived bacteria were then able to form the precipitation of further calcium carbonate. Additionally, the bacterium was able to go through cycles of self-healing multiple times without its activity being significantly affected. Also presented are experiments in particulate media which showed the ability of the organism to cause the cementation of sand columns. S. ureae was able to respond when a physical or chemical damage occurred to the monolith by germinating and producing again calcium carbonate which restored the functionality of the bio-cemented sand columns.

Full textAbstract:
Oxidation of pyrite can significantly affect properties and the behavior of soil and rock in civil construction. Problems with pyritic rock and soil extend globally and across many disciplines. Consequences of pyrite oxidation include heave, concrete degradation, steel corrosion, environmental damage, acid mine drainage, and accelerated weathering of rock with concomitant effects on strength and stability. Affected disciplines include soil science, mining, engineering geology, geochemistry, environmental engineering, and geotechnical engineering.
While pyrite problems may be well known in their respective disciplines, there has been to date relatively little cross-disciplinary communication regarding problems with pyritic geomaterials. Thus, there is a need to establish an inter-disciplinary and inter-regional awareness regarding the effects of pyrite oxidation and their prevention or mitigation.
This engineering research is a compilation of information about geotechnical problems and engineering behavior of pyritic rock and soil, the underlying physicochemical processes, site investigation strategies, and known problematic formations. Several case histories documenting consequences of pyrite oxidation are provided. The results of chemical analyses performed on pyritic shale samples from a formation with acknowledged heave problems are presented. Digital data and ESRIâ s ArcGIS digital mapping program were used to create maps showing results of sampling and testing performed during this study. Appendices include mitigation options, results of a practitioner survey, chemical test procedures, a glossary, a visual identification key for sulfidic geomaterials, and a summary table of the literature review for this research.

Full textAbstract:
Construction of underground structures in urban areas requires a detailed assessment of the associated movements imposed on adjacent structures and services and in particular of any damage that may be caused. The most efficient way of investigating these issues is through the application of advanced numerical analysis, using for instance the finite element method. However, for a useful analysis to be performed, a high quality ground investigation must be conducted in order to derive the necessary soil parameters for numerical modelling. This thesis focuses particularly on the case study of the Ivens shaft located near to the Baixa-Chiado station of the Lisbon Metro, Portugal. This is an underground structure of a complex shape and significant depth, situated in the centre of the city and it is therefore important to assess the influence of its construction on the existing adjacent structures and services. In the first part of the thesis the results of the geotechnical survey performed on the relevant Miocene formations located at the Ivens shaft site are presented and discussed. In particular, the “Areolas de Estefânia” formation was characterised in detail since this layer had not sustained significant investigation in the past, mainly due to difficulties in sampling. From the extensive characterisation undertaken, which included both field and advanced laboratory tests, it was possible to derive a suitable framework for the different formations in terms of strength and stiffness. Such information was then used to calibrate appropriate soil constitutive models for use in the numerical analyses. In this respect, the new generation of algorithms, known as Genetic Algorithms, was employed to increase the efficiency and accuracy of the calibration procedure. The second part of the thesis focuses on the 3D numerical modelling of the excavation of the Ivens shaft, which was performed employing the state-of-the-art software ICFEP (Imperial College Finite Element Program). The results obtained permitted the quantification of the shaft and ground movements and their effect on adjacent structures. Particular attention was given to the influence of the excavation on the Baixa-Chiado station and on the adjacent buildings founded near the ground surface. Finally, a parametric study was carried out in order to investigate a number of shaft parameters that may affect the movements and to provide more general guidance for shaft construction.

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOEm análises geotécnicas, previsões de deformações ou de fatores de segurança são desenvolvidas com base em métodos determinísticos, que admitem como fixos e conhecidos os parâmetros do solo ou da rocha. Entretanto, tais previsões são afetadas por incertezas provenientes da impossibilidade de reprodução das condições de campo em laboratório, da perturbação do solo devida à instalação de instrumentos, das ocorrências geomecânicas não detectadas durante a campanha de sondagens, da variabilidade inerente ao maciço, entre outras. O estudo da influência dessas incertezas sobre os cálculos determinísticos, com a possibilidade da quantificação do risco de insucesso associado a um projeto geotécnico, desenvolveu-se durante as últimas décadas com base nas teorias de probabilidade e estatística. O presente trabalho realiza uma revisão bibliográfica de conceitos básicos de probabilidade e estatística, mostrando alguns avanços da aplicação desses conceitos na engenharia geotécnica. Visando apresentar formas de estimarem-se probabilidades de recalque inadmissível ou de ruptura são realizadas análises para os seguintes casos: recalques de argila mole solicitada por aterro e de fundações superficiais em areia, estabilidade de fundação superficial em solo residual e de fundação profunda em solo sedimentar, deslizamento de um muro de arrimo e estabilidade de um talude. Com o objetivo de inferir acerca dos fatores que influenciam as estimativas probabilísticas, para cada caso são realizadas comparações entre resultados obtidos com base em diferentes métodos probabilísticos e/ou determinísticos.
In geotechnical analyses, forecasts of safety factors or deformations are developed on the basis of deterministics methods, that admit as fixed and known the parameters of the soil or the rock. However, such forecasts are affected by uncertainties proceeding from the reproduction impossibility of the field conditions in laboratory, of the disturbance of the soil under installation of instruments, of the not detected geomechanics occurrences during the soundings campaign, of the inherent variability to the soil, among others. The study of the influence of these uncertainties on the deterministics calculations, with the possibility of the risk quantification of failure associated with a getechnical project, developed during the last decades on the basis in theories of probability and statistics. The present work make a bibliographical revision of basic concepts of probability and statistics, showing some advances of the application of these concepts in geotechnical engineering. With the objective to show forms of computing probabilities of rupture or of inadmissible settlement are make analyses for the following cases: settlement of fill on soft clay, settlement of superficial foundations in sand, stability of superficial foundation in residual soil, stability of deep foundation in sand, stability of retaining wall and dam slope stability. With the objective to verify the factors that influence the probabilist estimates, for each case is make comparisons between results given of different probabilist and/or deterministics methods.

Full textAbstract:
A relatively new concept of Municipal Solid Waste treatment is known as bioreactor landfill technology. Bioreactor landfills are sanitary landfills that use microbiological processes purposefully to transform and stabilize the biodegradable organic waste constituents in a shorter period of time. One of the most popular types of bioreactor landfills is the landfill with leachate recirculation. However, it is observed that ammonia rapidly accumulates in landfills that recirculate leachate and may be the component that limits the potential to discharge excess leachate to the environment. In the facultative landfill, leachate is nitrified biologically using an on-site treatment plant and converted by denitrifying bacteria to nitrogen gas, a harmless end-product. In this research, three pilot-plant scale lysimeters are used in a comparative evaluation of the effect of recirculating treated and untreated leachate on waste stabilization rates. The three lysimeters are filled with waste prepared with identical composition. One is being operated as a facultative bioreactor landfill with external leachate pre-treatment prior to recirculation, the second is being operated as an anaerobic bioreactor landfill with straight raw leachate recirculation, and the third one is the control unit and operated as a conventional landfill. Apart from environmental restrictions, geotechnical constraints are also imposed on new sanitary landfills. The scarcity of new potential disposal areas imposes higher and higher landfills, in order to utilize the maximum capacity ofthose areas. In this context, the knowledge of the compressibility of waste landfills represents a powerful tool to search for alternatives for optimization of disposal areas and new solid waste disposal technologies. This dissertation deals with and discusses the environmental and geotechnical aspects of municipal solid waste landfills. In the Environmental Engineering area, it compares the quality of the leachate and gas generated in the three lysimeters and discusses the transfer of the technology studied through lysimeters to procedures for full-scale operation. In the geotechnical area, this dissertation discusses the compressibility properties of the waste and provides a state-of-the-art review of MSW compressibility studies. It also evaluates the compressibility of MSW landfills for immediate and long-term settlements and proposes a new model for compressibility of waste landfills.
