Page, Jonathan. "Changes in lateral stress during slurry trench wall installation". Thesis, Queen Mary, University of London, 1996. http://qmro.qmul.ac.uk/xmlui/handle/123456789/1650.
Texto completoResumen
The thesis is concerned with the effects of slurry trenching (diaphragm wall installation) in an overconsolidated clay, with particular emphasis on the changes in lateral stress which occur. A review of the literature on diaphragm wall installation in stiff overconsolidated clay was carried out, with particular reference to the measurement of changes in stress and the application of finite element analyses. The problem was investigated by means of centrifuge model tests and finite element analyses. The main body of the thesis details the development and results of a series of centrifuge tests. A model at 1 to 100 scale was tested at 100 gravities, enabling both the long and short term effects of slurry trench walling to be investigated. The technique adopted used a fluid-filled neoprene rubber bag in the place of the trench that was drained to ground level to simulate excavation under bentonite slurry. A mixture of plaster of Paris, iron-filings, fine sand and cement powder was then deposited into the bag to simulate wall placement. By using different fluid heights of different densities in the rubber bag, a series of initial earth pressure coefficients were modelled. The effects of both a stress and strain controlled boundary at the remote end of the model were also investigated. Finally, simulated concretes of different densities were adopted to see what effect this would have on placement stresses. A technique was developed to enable the measurement of changes in total lateral stress changes at up to 10 locations within the model. Pore water pressures were measured at the same positions, and ground settlements were measured at the surface of the model. A series of finite element analyses was carried out to extend the scope of the centrifuge model results by varying further the initial in situ conditions. The conclusions and suggestions for further work are presented at the end of the thesis.

Texto completoResumen
Slurry walls have been widely used for more than 25 years to control the migration of contaminants in the subsurface. In the USA, vertical barriers are mostly constructed of soil-bentonite using the slurry trench method of construction. In this method, sodium bentonite is mixed with water to form a viscous slurry that is pumped into a trench during excavation to maintain the trench stability. The stable trench is then backfilled with a mixture of soil and slurry having a consistency of high slump concrete. These barriers have been designed primarily for low permeability, generally less than 10&minus9 m/s. Some investigations have pointed toward improved performance using admixtures that would provide low permeability. In this study, Soma thermal power plant fly ash, granulated blast furnace slag, lime, and steel slag are used as admixture to improve the performance of slurry walls. Permeability, compressive strength, slump, compressibility properties of the mixtures were found and checked for the minimum requirements. According to the findings of this study, granulated blast furnace slag (GGBS), fly ash and steel slag can be used at certain percentages and curing periods as additive in cement-bentonite barrier wall construction. Permeability of specimens having fly ash decreases by increasing fly ash content. Mixtures having 50 % of GGBS type I with 5 % of lime and 9% bentonite content gave acceptable results in 28 days of curing time. Specimens including 50 % of GGBS type II with 5 % of lime and 9% bentonite content gave the higher permeability value in 28 days of curing time with respect to GGBS type I. In addition, most of the mixtures prepared by steel slag gave the acceptable permeability values in 28 days of curing period. Unconfined compressive strength of all mixtures increase by increasing curing time. Cc, Cr, Cv, kcon values were found from consolidation test results. Permeability values found from consolidation tests are 10 times to 100 times higher than flexible wall k results for the same effective stress of 150 kPa. Generally, mv values are decreasing with increasing curing time. As mv decreases, D increases.

Texto completoResumen
Västlänken i Göteborg är ett tunnelprojekt för järnväg som skall byggas under centrala Göteborg. Tunneln byggs genom både berg och lera, projektet kommer att använda sig av ett flertal tekniker och konstruktionslösningar. Västlänken är ett av de första stora infrastrukturprojekt i Sverige där slitsmurar används som permanenta konstruktioner. På uppdrag av Trafikverket har två olika typer av stödmurskonstruktioner undersökts med avseende på deras klimatpåverkan. Konstruktionslösningarna är en temporär spont med tillhörande tunnelvägg och en slitsmur. Slitsmuren används både som en temporär konstruktion under byggskedet och en del i den permanenta tunnelväggen. Slitsmurar har först nyligen blivit godkända att användas som delar av permanenta konstruktioner av Trafikverket. Av denna anledning finns det inte mycket information om konstruktionens klimatpåverkan. Syftet med rapporten är att undersöka klimatpåverkan från de två olika konstruktionslösningarna. Jämförelsen har gjorts med hjälp av livscykelanalyser för att få den mest övergripande analysen. En livscykelanalys (LCA) är ett verktyg för att synliggöra en produkts totala miljöpåverkan under dess livstid. Detta åstadkoms genom att alla de olika delprocesser som krävs för att skapa produkten inventeras och analyseras. LCA har utförts med datorprogrammet SimaPro och databasen Ecoinvent. I SimaPro har båda konstruktionslösningarna modellerats och deras miljöpåverkan sedan beräknats med ReCiPe 2016. Indata till LCA har samlats in från ritningar och diskussioner med experter på området. Resultatet från livscykelanalysen visar att slitsmurarna i detta projekt har större klimatpåverkan än konstruktionslösningen med spont och en platsgjuten betongmur. För slitsmuren står armering samt betong för den största delen av klimatpåverkan och för sponten är det den stora mängden stål som krävs vid de kraftiga dimensionerna. Då en del av konstruktionerna inom projektet ej var färdigprojekterad när denna rapport författades rekommenderas ytterligare studier på ämnet för att validera resultatenThe West Link Project is as tunnel project for the railroad that will be constructed below central Gothenburg. The project is built through clay and solid rock thus making use of several techniques and structural solutions. The West Link Project (Västlänken) is the first major infrastructure project in Sweden where diaphragm walls are used as a part of the permanent structure. Two different structures have been examined on behalf of the Swedish Transport Administration, with regards to their climatic impact. The two structures examined are a temporary sheet pile with a cast-in-place concrete wall that is used as a part of the tunnel wall, and a diaphragm wall. The diaphragm wall is used as an earth retaining wall during the construction stage and as a part of the permanent tunnel wall. Diaphragm walls have just recently been approved as parts of permanent structures by the Swedish Transport Administration. Due to this there isn’t a lot of information available on their climatic impact. The purpose of this paper is to examine the climatic impact of these two different structures. The comparison has been performed by the use of a lifecycle analysis to get the most comprehensive analysis. A lifecycle analysis (LCA) is a tool that helps to get a perspective on a product’s total environmental impact over the course of its lifetime. This is accomplished by doing an inventory of all the different processes involved in its production. For the LCA the computer program SimaPro, and the database Ecoinvent were used. In SimaPro both of the structure have been modelled and their environmental impact has been calculated with ReCiPe 2016.Input for the LCA have been gathered from drawings and communication with experts. The result of the LCA shows that in this project the diaphragm walls have a higher climatic impact than the sheet pile and concrete wall. With regards to the diaphragm wall the majority of its climatic impact is from the large amounts of reinforcement and concrete used. For the sheet pile the steel used to manufacture sheets of the dimensions used in the project is the largest contributing factor. Due to the fact that some of the structures in the project are still being at the design stage at the time of writing further studies are recommended to validate the results.

This thesis evaluates the measured performance of 29 slurry wall supported excavations in Boston, Chicago, Washington DC, and San Francisco - most of which have been constructed since 1980. Each of these case studies includes data on the initial site conditions (soil profile and properties, groundwater conditions and location of adjacent facilities etc.) and designs for support of the excavations. The main goal is to relate construction records to the measured performance of the lateral earth support systems. The principal parameters of interest are the induced ground deformations (and their effects on adjacent structures) and observations of groundwater flows. The actual monitoring data always include inclinometer measurements of lateral deflections within the diaphragm wall and/or adjacent soil. However, other information such as surface settlements, building settlements, heave of the sub-grade or piezometric data were only archived for some of the projects (nearly all in Boston). Even fewer projects contain measurements of structural forces in either the diaphragm wall or bracing system. These data have been grouped according to the soil profile, toe fixity of the wall and type of bracing system (tie-back anchors, prestressed cross-lot and top-down). Most of the projects have succeeded in allowing only small wall deflections, often less than 0.2% to 0.3% of the total excavation depth, and similar magnitudes of the maximum surface settlements. Larger wall movements did occur in several projects but have been linked to either inadequate bracing (poor tieback design or inadequate pre-stressing of rakers), lack of toe embedment or ground softening inside the excavation (installation of drilled caissons or load bearing elements). Unexpectedly large surface settlements in one project (Dana Farer) were clearly linked to ground loss during tieback installation. Several other reported cases of leakage (through panel joints and/or tiebacks) have been repaired by grouting. Given the limited availability of archival data, the thesis has focused on the interpretation of lateral deflections. Wall deformations have been sub-divided into rigid body translation, rigid body rotation and bending modes. Empirical correlations have been proposed for estimating each of these components.

O presente trabalho investigou o comportamento mecânico e hidráulico de novos materiais geotécnicos compósitos para a utilização em barreiras verticais do tipo Slurry Walls. Fundamentalmente, o objetivo do programa experimental foi analisar o comportamento tensão-deformação e a influência da poro-pressão, através de ensaios triaxiais e ensaios de compressão não-confinada em misturas solo-cimento-bentonita (SCB) e solo-cimentobentonita- fibra (SCBF) e também a condutividade hidráulica em misturas solo-bentonita-fibra (SBF) e solo-cimento-bentonita-fibra. As misturas testadas nos ensaios triaxiais, cisalhadas na condição não-drenada (CIU) com tensões efetivas entre 50 e 470 kPa, foram rompidas após um período de 7 dias de cura. Nestes ensaios, foram medidas as condutividades hidráulicas antes e após o cisalhamento dos corpos de prova, a fim de comparar e identificar o comportamento da condutividade quando as barreiras verticais são solicitadas.A condutividade hidráulica avaliada em permeâmetro de parede rígida para as misturas SBF e SCBF foram comparadas com resultados de misturas SB e SCB obtidos na literatura. Os resultados dos ensaios realizados indicaram uma mudança dos padrões de comportamento dos materiais compósitos em relação à situação sem reforço, como o aumento dos parâmetros de resistência ao cisalhamento e a diminuição das deformações volumétricas sob carregamento isotrópico. Os ensaios de condutividade hidráulica confirmaram que o comportamento do material não foi afetado pela adição das fibras. Já os ensaios de condutividade hidráulica realizados no equipamento triaxial demonstraram que a condutividade hidráulica aumenta após o cisalhamento do corpo de prova.The present work aimed the investigation of the mechanical and hydraulic behavior of new geotechnical composite materials for use in vertical barrier walls (Slurry Walls). Fundamentally, the objective of the experimental program was to analyze the stress-strain behavior as well as the pore-pressure influence by means of triaxial tests, unconfined compression tests on mixtures of soil-cement-bentonite (SCB) and soil-cement-bentonitefiber (SCBF), and hydraulic conductivity tests on soil-bentonite-fiber (SBF) and soil-cementbentonite- fiber mixtures. The speciments formatted by the different mixtures were tested in the triaxial equipment, and sheared under consolidated isotropically undrained conditions (CIU) and efective stresses ranging from 50 to 470 kPa, after 7 days of curing. In these tests, the hydraulic conductivities were measured previously and after shearing the samples, in order to compare and identify the conductivity behavior at the moment in which the vertical barriers are requested. The hydraulic conductivity coefficients of SBF and SCBF mixtures obtained from rigid wall permeameter tests were compared with results existent in the literature for SB and SCB mixtures. The results indicated changes of the behavior standards for composite materials if compared with the unreinforced situation, such as increases of shear strength parameters and decreases of volumetric deformations under isotropic loading. The results of hydraulic conductivity tests confirmed that the behavior of the material is not affected by the addition of fibers. The results of hydraulic conductivity tests conducted in the triaxial equipment showed increases of the hydraulic conductivity coefficient after the shearing of the samples.

The topic of this diploma thesis is to revitalise of one city block and to maximise of its utilisation with combination of many different functions on this concrete area. This work is based on pre-diploma project in previous semester. This project ensures many possible functions for the inhebitants and also reflects natural differentiation between privat and public usage with impact on high quality of living space and appropriate public transport. Designed build-up area is situated betveen Veveri, Kounicova and Pekarenska streets in Brno. Patterns of this area are essential for the treatment of this project when both diagonaly and verticaly crosses whole area. Substance and space treatment reflects nearby structures and is naturally connected to it. Main substance of object is divided to three blocks via communications which crosses the area. Innerblock is sedated with green vegetation, connected to transit parter with shops and services. On the parters roof there is green walk-designed cover for inhabitants and after there are higher houses. Whole building complex is closed with rambling fractional roof covers with terraces of storeyed flats. This space structure is horizontally divided by its functions. In this project there are underground garages, shops and services, administrative spaces and space for rent and mostly flats for living. Fundamental look of the building is created by external rendering covering most of building which is connected to nearby structures. Shopping mall and separate blocks and also entrances to buildings and terraces/balcony are formed by taking off the substance by which leads to its fractionalism.

An optimization approach is presented in this paper for the design of reinforced concrete slurry wall. The design criteria are based on ACI Building Code (318-95) requirements, Building Regulations of ROC (1997) and Design Code of Practice for Foundations(1998). The design method of this thesis is based on the working stress design and ultimate strength design methods. The design variables include the thickness, embedded length, tension reinforcement, shear reinforcement, shrinkage reinforcement, splice length and development length. The minimum cost of construction of slurry wall based on the costs per unit volume of the concrete and the steel is taken as the objective function. The constraints include the requirements such as the thickness of wall, flexural strength, shear strength, ductility, the balance of active and passive earth pressure, heaving, boiling, splice length and development length of steel bars. The optimal approach utilized in this thesis is the GRG method of nonlinear programming. The results from this study may provide as a useful reference for the engineering design.

Due to the variable properties of slurry suspension, the cave-in of slurry trench and poor field work, the concrete of diaphragm wall may present the defects by embedded with soil, fluid and honeycomb, and by the mud cake between wall units. These defects will allow the groundwater to seep through. Therefore, a nondestructive integrity testing can be conducted to detect the defect of concrete wall, and the grouting can be followed to seal the seepage channels before the basement excavation. This may prevent the possible piping failure. To be able to identify types of defects, the standard cylindrical concrete samples and four units of concrete diaphragm walls containing various defects with known positions, sizes and types are prepared. The changes of pulse velocity when the sonic wave travelling through concrete with various defects by cross-hole sonic logger testing are used to find the location of defects. The result of spectrum analysis and variation of amplitude are analyzed for each type of defect. Furthermore, the attenuation property for various defects is studied by evaluating the energy ratio, and these results may serve as a basis to identify the type of defect. In addition, the relationship between concrete strength and pulse velocity is established by sonic and unconfined compression testing.

This thesis develops a discrete-event simulation model for scheduling slurry wall constructions which posse the properties of repetitive projects. This model considers the activities in various panels of a slurry wall construction which have there own duration distributions, so as to simulate the practical construction of a slurry wall. And further, this model considers both factors of the logic relationships of the interrelated activities and resources are available in limited quantities in the process of a slurry wall construction. This model also integrates the specific decision variables of the slurry wall construction to experiment on computers with the stochastic simulation method. More over, with the next event algorithm(NEA) and the backward pass algorithm(BPA) what representing the means of the resources being used(as soon as possible or inverse way), the scheduled timing and the efficiency of the specific resources and proper floats of each activity in a slurry wall construction can be calculated. Finally, a numerical example is used to illustrate the applications of this model.

Current lateral earth pressure diagrams in the design were generally based upon the measurements obtained from sheet pile wall and soldier beam-wood lagging retaining wall systems. Those retaining systems are relatively less rigid compared with the current widely used reinforced concrete slurry wall system. However, the influence of wall rigidity on the behavior of retaining wall system is unknown. Therefore,the objective of the study is to investigate the stability and lateral earth pressure distribution of reinforced concrete slurry wall system by using the finite element analysis. The behavior of an interface element was investigated in order to provide sufficient information to simulate the relative displacement at the contact surface between soil and retaining wall system. The stability of slurry wall system was also investigated by using current design methods for better understanding of the physical meaning of the results obtained from the finite element analysis. A series of direct shear tests and finite element analyses were performed to investigate the frictional behavior among three types of soils and four different kinds of retaining wall materials. The results of the study shown that the frictional behavior at soil-retaining wall system can be simulated by using an exponential function that consists of two control variables, which are shear modulus (C exp) and displacement modulus (l). For the conditions of analyzed, the shear moduli varied from 0.415 to 0.425 and the displacement moduli varied from 0.002 to 0.008, respectively. Generally, shear modulus of 0.42 and displacement modulus of 0.002 are recommended to be used in the finite element analysis. The embedment analysis for deep excavation of slurry retaining wall system was performed by using NACFAC procedure and the finite element analysis. The results of the analysis shown that the embedment of 0.3 - 0.4 times of excavation depth is sufficient by using NACFAC procedure. However, the results obtained from the finite element analysis indicated that the embedment of 0.8 - 1.0 times of excavation depth is required to maintain the stability of the deep excavation.In the NACFAC procedure of embedment analysis, the stability of the retaining wall system is based upon the ratio of the resistance moment over the driving moment at the bottom supporting hinge. The entire flexure strength of the retaining wall system is included in resistance moment in the analysis. However, the developed resistance moment of reinforced concrete slurry wall system is depend upon the deflection of the retaining wall. Therefore, the current NACFAC procedure is required some modification in t he embedment analysis for reinforced concrete slurry system. A comparison among various lateral earth pressure diagrams was made in the study. The results of the analysis shown that the variation of the total strut forces calculated by different diagrams is very minimum. However, it is not recommended to use Tschbotariff method to estimate lateral strut forces of retaining wall system in dense sand. According to the results of finite element analysis, the rigidity of retaining wall system has significant effect on the lateral earth pressure distribution of retaining wall system. If the rigidity of the retaining wall is only 1% of reinforced concrete stiffness, the lateral earth pressure distribution is quite similar to that observed from sheet pile wall system. However, the lateral earth pressure diagram of reinforced concrete retaining wall system is quite similar to Rankine active earth pressure diag ram. Therefore, it is recommend that the apparent lateral earth pressure diagram based upon the observation from sheet pile wall system should not to be used in the design of slurry wall system.
