Abstract:

With ever increasing energy demand and related climate change implications, the development of sustainable energy systems based on integrated schemes of energy production, transport, transfer, and storage is an important challenge to society. The broad and emerging area of Energy Geotechnics has the potential to address this challenge from multiple perspectives by integrating concepts from geotechnical engineering and geomechanics with cross-disciplinary concepts from geology, hydrology, geophysics, geochemistry, petroleum engineering, and energy policy. The 2nd International Conference on Energy Geotechnics is organized by the members of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) Technical Committee 308 on Energy Geotechnics, and is the main international venue for interaction, communication, and technology transfer for academic and non-academic parties, including researchers and practitioners, in the broad areas within Energy Geotechnics

Abstract:

Abstract BAYANAL code in geotechnical design based on Eurocode 7. Geotechnical problems that are characterized by a high degree of complexity and uncertainty with respect to the input data are solved recently, using the Bayesian analysis (for instance the problem of a cautious estimation of the geotechnical characteristic parameters according to the Eurocode 7 requirements). The applicability of the Bayesian approach to geotechnics via a simple examples related to determination of characteristic values of geotechnical parameters for design structures is in the paper addressed. In order to select the characteristic parameters for the geotechnical design a new numerical code called BAYANAL was developed. Example of applying the BAYANAL code to analyse the DMT tests demonstrates that it is a powerful and promising tool in evaluation of ground properties and geotechnical parameters.

Abstract:

Fixed endpoint problems (FEPPs) in constrained systems like the effect of curing time or the effect of certain additives in soil stabilization operations have been reviewed illustratively for sustainability purposes in geotechnics. The calculus of variation (CoV) technique of Hamilton’s problem was demonstrated using a typical case in geotechnics; the effect of curing time on the unconfined compressive strength of expansive soils is utilized as foundation materials. The era of smart technologies is evolving, and to key into this fast-moving area to help the field of geotechnics, it is required that these new areas are deployed to study their usefulness. The use of CoV in modeling or simulating geotechnical properties of soil behavior is not prominent and has been played down due to the uncertainties surrounding it. However, this work has identified that if any geotechnical system can be demonstrated in graphs, then the use of CoV becomes easy with the mathematical concept that curves are elements of straight paths. The results of this work show that CoV is a powerful tool to achieving sustainable optimization of quality properties of stabilized for sustainable and optimal materials handling, design, and construction.

Zusammenfassung Geomechatronik bezeichnet das Zusammenspiel von Geotechnik, Maschinenbau, Mess-, Steuerungs- und Regelungstechnik. Durch ein verbessertes Verständnis der Prozesse in der Geotechnik kann es gelingen, den Prozess und die Baumaschinen zu optimieren und den Herstellungsprozess durch Kennwerten zu charakterisieren. Diese Messwerte können dann zur Steuerung und Regelung der Prozesse zielgerichtet genutzt werden. An vier Beispielen, nämlich der Einbringung von Profilen, dem Ziehen von Bohrwerkzeugen, der gezielten nachträglichen Verpfropfung von vibrierten, offenen Profilen und der Rütteldruckverdichtung wird der Ansatz erläutert. Ein weiteres Beispiel zeigt auf, wie die einzelnen Prozesse auf einem beengten Baufeld automatisiert werden können. Erläutert wird hierfür die Methode der Zellulären Automaten in Verbindung mit der Graphentheorie. * The Vienna – Terzaghi Lecture was held at the 12th Austrian Geotechnical Conference at the end of January 2019.

Abstract:

Bad choice of construction site or poor number or local geotechnical study test lead to construction ruin; hence the need to have a geotechnical map for each urban area, which will constitute a reference for urban planners. Urban geotechnics is the study of urban land environments to provide a scientific and technical database for rational urban development and land use planning. The aim of this work is to make an inventory of all potential geotechnical problems in the soil bounded by the urban perimeter of Beni Ensar city. So to characterize the soil many geotechnical tests carried out in the laboratory and in situ are analysed. The results of these geotechnical tests are represented geo-spatially using GIS software. The thematic maps obtained will constitute a reference to the planners and the various actors in this field to adapt development plans and types of buildings to the properties of the supporting soil. They will also allow the civil engineering laboratory to optimize the choice of the study method and the types of tests.

Abstract:

AbstractThe effect of time on soil properties, noticeable in many earthworks, is recognized by geotechnicians. For example, secondary compression and aging pre-consolidation are considered in geotechnical design, and strain rate is standardized in geotechnical laboratory and field tests. Elastic-plastic models, from rigid-perfect plastic to Modified Cam Clay, which do not consider the effects of time, solve most geotechnical problems. However, solutions for prolonged settlements, landslides, debris flow and mudflow could profit from a deeper understanding of rheological models. In fact, rheological concepts, despite not always clearly stated, have been used to address some of these problems, and may also be important for using new materials in geotechnical practice (tailings, sludge, soil-polymer mixtures and other materials with water content higher than the liquid limit). This paper introduces basic concepts of rheology for geotechnicians, specially highlighting viscoelasticity under simple shear stress, which explains with reasonable accuracy well known phenomena dependent on time in soils. The objective is to bring geotechnicians to rheology and show another important tool to access geotechnical problems. On the other hand, a brief explanation of geotechnical tests is presented for rheologists not acquainted with geotechnical engineering. Geotechnical tests procedures are discussed in the light of rheology concepts, terminology is clarified, examples of application of rheology in geotechnics are presented, and determination of soil rheological parameters by traditional geotechnical tests as well as by tests on concrete is commented.

Abstract:

The use of optimization methods in geotechnics dates back to the 1950s. They were used in slope stability analysis (Bishop) and evolved to a wide range of applications in ground engineering. We present here a non-exhaustive review of recent publications that relate to the use of different optimization techniques in geotechnical engineering. Metaheuristic methods are present in almost all the problems in geotechnics that deal with optimization. In a number of cases, they are used as single techniques, in others in combination with other approaches, and in a number of situations as hybrids. Different results are discussed showing the advantages and issues of the techniques used. Computational time is one of the issues, as well as the assumptions those methods are based on. The article can be read as an update regarding the recent tendencies in the use of optimization techniques in geotechnics.

Abstract:

Over the years, the field of geotechnical engineering focused on physical, chemical and mechanical aspects of the geomaterials. However, recent developments in environmental geotechnics have highlighted the impact of biological processes on geo-materials and their performance. Also, the present day geotechnical problems favour biological interventions to develop eco-friendly and sustainable technology. In view of this, the present study is a preliminary investigation on the impact of microbial loading on fine-grained soils. In addition, a protocol has been developed to establish ‘bio-geo interface’ between bacteria and the geo-material. However, long term studies are demanded in this direction for in-depth understanding of the mechanism for development of prospective application.

Abstract:

Abstract A hypoplastic approach to constitutive modelling was developed by Kolymbas 1996 considering a non-linear tensor function in the form of strain and stress rate. However, the implicit formulation of the hypoplastic model with indirect material parameters severely limits its applicability to real-world geotechnical problems. In many cases, the numerical analysis of geotechnical problems relies on simple elastoplastic constitutive models that cannot model a wide range of soil response aspects. One promising paradigm of constitutive modelling in geotechnics is hypoplasticity, but many of the hypoplastic models belong to advanced models. In the article, we present the simple hypoplastic model as an alternative to the widely used Mohr-Coulomb elastoplastic model.

Abstract:

Abstract With increasing awareness of geotechnical risks in civil and mining structures, taking advantage of smartphone technology to study rocky slopes can play a key role in the development of safe and economical structures for human welfare. In Malawi, there is a research gap on application of portable devices to collect geotechnical data. Geological engineers still use the unsafe tedious handmapping technique to collect geotechnical data. A road cut that experiences frequent rockfall is used as a case study to investigate if there is a role for smartphones in geotechnics by comparing set statistics of data clusters collected through photogrammetry, smartphone and clar inclinometer. Besides low cost, smartphone’ data capture speed is faster than clar inclinometer. Stereographic and kinematic analysis shows that the 75° dipping road cut is predominantly prone to wedge failure with minor planar failure. For slope stability, Q-slope suggests a new slope angle of 60–66°. An acceptable tolerance limit or error between handmapping and remote data capture systems should be less than ±15°. Set analysis on 111 comparable data points gave a maximum pole vector difference of 10.5°, with the minimum having a difference of 4.8°. For dip, the standard deviations vary from 4.9 to 9.5°, while their mean values vary from −2 to 2.75°. For dip directions, the standard deviations vary from 3.2 to 4.3°, while their mean values vary from −6 to 0.75°. Therefore, android smartphones have a role in geotechnics due to their allowable orientation errors, which show less variance in measured dip/dip direction.

Abstract:

Abstract The design process in geotechnical engineering requires the most accurate mapping of soil. The difficulty lies in the spatial variability of soil parameters, which has been a site of investigation of many researches for many years. This study analyses the soil-modeling problem by suggesting two effective methods of acquiring information for modeling that consists of variability from cone penetration test (CPT). The first method has been used in geotechnical engineering, but the second one has not been associated with geotechnics so far. Both methods are applied to a case study in which the parameters of changes are estimated. The knowledge of the variability of parameters allows in a long term more effective estimation, for example, bearing capacity probability of failure.

Abstract:

Recently, geotechnical problems that are characterized by a high degree of complexity and uncertainty with respect to input data have been solved using Bayesian analysis. One example is the problem of cautious estimation of geotechnical parameters according to Eurocode 7 requirements. The research included various types of soil such as peat, gyttja, organic mud, and clays. These were studied in order to develop an empirical correlation for determining the unit weight of mineral and organic soils. The compiled database of documented field research sites for different types of soil was used to investigate and develop direct relationships between measured results and dilatometer (DMT) readings, i.e., po and p1 together with pore water pressure (uo) and pressure (Pa). The soil unit weights were determined for both mineral and organic soils. The paper addresses the applicability of the Bayesian approach in geotechnics via a simple example related to the determination of characteristic values of geotechnical parameters for design structures. The results show that it is possible to conduct a more reliable forecast with improved statistical measures compared to other available methods for multilayer subsoils.

Abstract:

This work reviews the transient two-phase flow in porous media with engineering applications in Geotechnics. It initially overviews constitutive relationships, conventional theories, and experiments. Then, corresponding limitations are discussed according to conflicting observations and multiphase interfacial dynamics. Based on those findings, the dynamic nonequilibrium effects were so defined, which could also be abbreviated as dynamic/transient effects. Four advanced theories have already been developed to resolve these effects. This review collects them and discusses their pros and cons. In addition, this work further reviews the state-of-art in terms of experimental methods, influential factors in dynamic/transient effects, and modelling performance, as well as micromodel and numerical methods at pore-scale. Last, the corresponding geotechnical applications are reviewed, discussing their applicability in effective stress, shear strength, and deformation. Finally, the entire review is briefed to identify research gaps in Geotechnics.

Abstract. This paper proposes a Multidisciplinary Decision Support System (MDSS) as an approach to manage rainfall-induced shallow landslides of the flow type (flowslides) in pyroclastic deposits. We stress the need to combine information from the fields of meteorology, geology, hydrology, geotechnics and economics to support the agencies engaged in land monitoring and management. The MDSS consists of a "simulation chain" to link rainfall to effects in terms of infiltration, slope stability and vulnerability. This "simulation chain" was developed at the Euro-Mediterranean Centre for Climate Change (CMCC) (meteorological aspects), at the Geotechnical Laboratory of the Second University of Naples (hydrological and geotechnical aspects) and at the Department of Economics of the University of Naples "Federico II" (economic aspects). The results obtained from the application of this simulation chain in the Cervinara area during eleven years of research allowed in-depth analysis of the mechanisms underlying a flowslide in pyroclastic soil.

Abstract The geotechnical monitoring of the slope deformations is widespread at present time. In many geological localities and civil engineering construction areas, monitoring is a unique tool for controlling of negative factors and processes, also inform us about actual state of rock environment or interacting structures. It is necessary for risk assessment. In our case, geotechnical monitoring is controlling rockslide activity around in the future part of motorway. The construction of new highway route D1 from Bratislava to Košice crosses the territory which is affected by a massive rockslide close to Kraľovany village. There was a need to monitor the activity of a large unstable rockslide with deep shear planes. In this case of underground movement activity, the Department of Geotechnics of the University of Žilina installed inclinometers at the unstable area which worked on Time Domain Reflectometry (TDR) principle. Based on provided measurements, effectivity and suitability of TDR inclinometers for monitoring of deep underground movement activity is demonstrated.

Abstract:

In recent years, the use of electrical methods has been improved considerably in several areas such as environment, agronomy, geophysics and geotechnics. Electrical resistivity may be used as a parameter in soil characterization; it may have many advantages for the determination of geotechnical factors influencing the behavior of soil. In this research, laboratory tests were carried out on natural sodic soil from the region of Ain Nouissy (Mostaganem) to investigate the geotechnical and chemical behavior of a natural soil using electrical resistivity measurements under various conditions. This study aims therefore to identify relationships between electrical resistivity of the soil and some physical and chemical parameters such as water content, porosity, salt concentration and pH. Moreover, electrical resistivity has been measured with the addition of salts into the natural soil. The results show that electrical resistivity reduced drastically with the addition of salt. The obtained results will be used to evaluate properties needed for soil characterization, as well as to track soil behavior with respect to salt concentration for use in soil remediation.

Abstract:

Fünf Jahre nach Erscheinen des ersten Bandes der Fachzeitschrift Bauingenieur im Jahre 1920 wurde das fundamentale Buch „Erdbaumechanik“ von K. Terzaghi veröffentlicht. Letzteres wird weltweit als Geburt der modernen „Bodenmechanik“ angesehen, die als wesentlichste Grundlage der heutigen „Geotechnik“ gilt. In diesen Jahrzehnten hat sich die Geotechnik zu einem Hauptpfeiler des Bauingenieurwesens entwickelt. Dabei wandelte sich die zunächst revolutionäre Phase allmählich in eine evolutionäre, und zwar sowohl in der Theorie als auch in der Praxis. Der Artikel geht auf diese Entwicklung an Hand einiger Beispiele ein und hebt auch die vergleichsweise hohen Risiken in der Geotechnik sowie das geotechnische Risikomanagement hervor.

Abstract:

One of the main constraints in assessing shallow landslide hazards through physically based models is the need to characterize the geotechnical parameters of the involved materials. Indeed, the quantity and quality of input data are closely related to the reliability of the results of every model used, therefore data acquisition is a critical and time-consuming step in every research activity. In this perspective, we reviewed all official certificates of tests performed through 30 years at the Geotechnics Laboratory of the Earth Science Department (University of Firenze, Firenze, Italy), compiling a dataset in which 380 points are accurately geolocated and provide information about one or more geotechnical parameters used in slope stability modeling. All tests performed in the past (in the framework of previous research programs, agreements of cooperation, or to support didactic activities) were gathered, homogenized, digitalized, and geotagged. The dataset is based on both on-site tests and laboratory tests, it accounts for 40 attributes, among which 13 are descriptive (e.g., lithology or location) and 27 may be of direct interest in slope stability modeling as input parameters. The dataset is made openly available and can be useful for scientists or practitioners committed to landslide modeling.

Abstract:

The finite element method (FEM) has become a standard tool for solving complex problems in geotechnical engineering. Many different advanced constitutive models for fine-grained soils have been developed in recent years, which can consider various phenomena of soil. Generally, the number of constitutive parameters increases with phenomena incorporated in the model, and their determination is one of the key issues in numerical modeling in geotechnics. Normally, experimental data, experience, and back analyses based on engineering judgment are used to arrive at appropriate input parameters for a particular model. However, this procedure is not always satisfactory, especially when the number of required input parameters is large. In this paper, a population-based algorithm has been used to determine the constitutive parameters for a geotechnical boundary value problem, namely a floating stone column foundation under an embankment. Measurements of surface settlements and excess pore-water pressures at different depths are available for calibration. A subsequent statistical assessment of the calibration results is followed to assess the quality of the identified parameters in dependency of the different set of measurements evaluated. As a major result of this research, measures of the utility and reliability of the constitutive models for further predictive computations can be estimated.

The paper covers historical material on the formation and development of schools of thought in geotechnical engineering in Kharkiv National University of Civil Engineering and Architecture (formerly known as Kharkiv Civil Engineering Institute), which came into being in 1934 with the establishment of the Department of Bases and Foundations. Particular emphasis is laid upon some personalities of the department; they are outstanding scientists and professors, such as F.O. Belyakov, S.Z. Saidakovsky, I.Ya. Luchkovsky, G.G. Strizhelchyk and others, who made a significant contribution to the formation of schools of thought in geotechnical engineering at the university. A particular contribution of the created research laboratory and the developed equipment for field methods of research into physical and mechanical properties of soils of bases for the foundations of building structures is singled out in the development of scholarly knowledge. The achievements of the renamed Department of Geotechnics, Underground and Hydrotechnical Structures are listed as of today, such as renovation of the educational and research laboratory of “Geotechnical Survey”, which has a governmental certification and allows scientists and students to perform high-quality laboratory work and conduct a full range of engineering and geological and hydrogeological surveys for construction; creation of a new research and technical subdivision of the department known as “Center for monitoring buildings and structures”, which conducts an instrument monitoring of the stress-strain state of the bases and foundations of construction projects using advanced equipment and software packages; availability of an IT classroom and licensed software, including SOFISTIK, a powerful German design software package, which allows researchers to provide high-level research and technical support for designing construction projects. The paper also clearly shows the advantages of training scientific staff and civil engineers in specialties 192 “Construction and Civil Engineering” and 194 “Hydrotechnical Engineering, Water Engineering and Water Technology" and, as a result, a considerable demand for KhNUCEA graduates from employers.

Abstract:

Zusammenfassung Der vorliegende Beitrag diskutiert Erfahrungen und Gedanken zur Einbeziehung der Geotechnik in den Prozess der Planung unter Verwendung des Building Information Modeling (BIM). Da die Geotechnik beziehungsweise die Baugrundbeschreibung in der Praxis des Bauingenieurs eine wesentliche Planungsgrundlage darstellen, ist es unumgänglich, im Rahmen einer BIM-konformen Planung auch das oder die Baugrundmodelle in das BIM-Gesamtmodell einzubinden. Da die Entwicklung des BIM bislang vordringlich im Hochbau lag, wird dieser Beitrag dazu genutzt, die aktuell mögliche Umsetzung von BIM in der Geotechnik zu diskutieren. Es werden verschiedene Entwicklungen des BIM-Baugrundmodells im Lebenszyklus eines Bauwerkes von der Planung bis zur Nachnutzung vorgestellt und verschiedene Potenziale aber auch Schwierigkeiten, die es zu lösen gilt, angesprochen. Letztlich wird anhand eines Praxisprojektes mit hoher Komplexität bezüglich des Baugrunds dargestellt, welche Bausteine optimaler Weise in ein BIM-Baugrundmodell eingepflegt werden könnten. Somit liegt das wesentliche Ziel dieser Publikation darin zu zeigen, dass die Einbindung des Fachmodells „Baugrund“ in das BIM-Gesamtmodell notwendig und (trotz in der Baupraxis teilweise vorhandener Einwände) auch möglich ist. Dem Leser werden sowohl die Notwendigkeit der Einbeziehung des Baugrundmodells in das BIM-Gesamtmodell als auch die Potenziale, die hieraus resultieren, verdeutlicht. Ein weiteres Ziel ist es, dass dem Leser die Besonderheiten einer 3D-Baugrundmodellierung verdeutlicht werden, da der Baugrund mit seinen üblichen Unsicherheiten und Variationen im Vergleich zu den anderen Fachdisziplinen mit üblicherweise klaren Vorgaben hinsichtlich zum Beispiel Geometrie und Material im BIM-Gesamtmodell eine besondere Stellung innehat.

The earthquake caused severe damage that extended over a large region, including the provinces of Limon and Cartago in Costa Rica and the province of Bocas del Toro in Panama. Areas most affected in Costa Rica were the alluvial plains along the Caribbean Coast located west, northwest and southeast of Limon. These areas underwent extensive soil liquefaction and soil failures. Soil liquefaction caused severe damage to roads, bridges, railways, ports, water systems and banana plantations. Geotechnical aspects of bridge and roadway damage are covered in Chapter 6—Bridges.
