Robin Chowdhury, Gautam Bhattacharya, Subhadeep Metya ... 790 pages - Language: ‎English- Publisher: ‎ CRC Press; 2nd edition (November, 2023) - ISBN-10: ‎1138000116 - ISBN-13:‎ 978-1138000117.

This second edition of Geotechnical Slope Analysis is an updated version of the original scholarly book. In this edition, concepts and applications have been thoroughly revised. In particular, the ‘Initial Stress Approach’ has been extended to 2D problems in a more rigorous manner. Additional solved numerical examples have been added in several chapters. More importantly, the meaning of the results is explored through interpretation.

The influence of initial stresses, pore water pressures and seismic forces has been explored not only on performance indicators such as the ‘Factor of Safety’ but also on the location of critical slip surfaces. In addition to these factors, it is shown that the chosen method of analysis may also have a significant influence on the location of the critical slip surface. Student exercises have been included in some chapters with a view to encouraging further study and research, and reference is often made to case studies of particular importance.

The best features of the book have been retained with continued emphasis on both deterministic and probabilistic approaches for quantifying slope performance. The traditional performance indicator such as ‘Factor of Safety’ can be complemented by the calculation of the ‘Reliability Index’ and the ‘Probability of Failure’. This book focuses on research studies concerning slope behaviour, the occurrence of landslides and the use of alternative methods of analysis and interpretation. The importance of uncertainties in slope performance and, more broadly, in geotechnical engineering is emphasised.

This book will be valuable to undergraduate and senior students of civil, mining and geological engineering as well as to academic teachers and instructors and also to researchers, practising geotechnical engineers and consultants.

Slope stability is always a very important topic in many developed and highly congested cities, particularly for many cities in China where slope failures have killed many people with significant loss of properties. The author has also participated in different types of slope stability research and consultancy works in different countries, and has published two books entitled "Soil Slope stability analysis and stabilization new methods and insights" and "Frontier in civil engineering, vol.1, Stability analysis of geotechnical structures" which are well favoured by many students, engineers and researchers. The author also frequently receives email about the details of the more innovative slope stability analysis methods, stabilization and monitoring system, as well as the procedures in the numerical implementation of some of the stability analysis methods. In views of the various improvements in the theory of slope stability analysis over the years, the author would like to write a new book on slope stability analysis and slope reliability analysis, and the new materials will be useful to both students, engineers as well as researchers. 

In this book, different methods of slope stability analysis will be discussed in a broad sense. Following that, the limit equilibrium and finite element methods will be discussed in more details, as these two methods are the methods commonly used for practical works. Detailed procedures for limit equilibrium analysis will be provided to aid the students in learning, while the program SLOPE2000 will be introduced for the solution of more complicated problems. Some interesting engineering cases will be illustrated in this book. The author will also try to introduce the use of distinct element slope stability method, which is a technique still far from practical applications, but it does offer some insights which are not possible with the other methods

Guidelines for Evaluating Water in Pit Slope Stability is a comprehensive account of the hydrogeological procedures that should be followed when performing open pit slope stability design studies. Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on the stability of rock slopes in open pit mines, this book expands on the hydrogeological model chapter in the LOP project’s previous book Guidelines for Open Pit Slope Design.

The book comprises six sections which outline the latest technology and best practice procedures for hydrogeological investigations. The sections cover: the framework used to assess the effect of water in slope stability; how water pressures are measured and tested in the field; how a conceptual hydrogeological model is prepared; how water pressures are modelled numerically; how slope depressurisation systems are implemented; and how the performance of a slope depressurisation program is monitored and reconciled with the design. Guidelines for Evaluating Water in Pit Slope Stability offers slope design practitioners with a road map that that will help them decide how to investigate and treat water pressures in pit slopes. It provides guidance and essential information for mining and civil engineers, geotechnical engineers, engineering geologists and hydrogeologists involved in the investigation, design and construction of stable rock slopes.

Charles A. Kliche ... 376 pages - Publisher: ‎ Society for Mining, Metallurgy, and Exploration; 2nd edition (August, 2018) - Language: ‎English - ISBN-10: ‎0873353692 - ISBN-13‏: ‎978-0873353694.

This book focuses on rock slope stability, with sections on geological data collection, geotechnical data collection and analysis, surface water and groundwater effects, kinematic and kinetic stability analysis, rock slope stabilization techniques, and rock slope instrumentation and monitoring.

Because of the discontinuous nature of rock, the design of stable rock slopes is as much an art as it is applied engineering. Experience can only be achieved from the proper utilization of these theories of soil and rock mechanics, structural geology, and hydrology. Rock Slope Stability is invaluable for engineering geologists, geotechnical engineers, mining engineers, civil engineers, and mine managers— as well as anyone else dedicated to engineering slopes that are stable and safe and that enable a financial return.

Zijun Cao, Yu Wang ... 190 pages - Publisher: Springer; 1st edition (August, 2016) ... Language: English - ISBN-10: 3662529122 - ISBN-13: 978-3662529126.

This is the first book to revisit geotechnical site characterization from a probabilistic point of view and provide rational tools to probabilistically characterize geotechnical properties and underground stratigraphy using limited information obtained from a specific site. This book not only provides new probabilistic approaches for geotechnical site characterization and slope stability analysis, but also tackles the difficulties in practical implementation of these approaches. In addition, this book also develops efficient Monte Carlo simulation approaches for slope stability analysis and implements these approaches in a commonly available spreadsheet environment. These approaches and the software package are readily available to geotechnical practitioners and alleviate them from reliability computational algorithms. The readers will find useful information for a non-specialist to determine project-specific statistics of geotechnical properties and to perform probabilistic analysis of slope stability.

Slope Stability Analysis by the Limit Equilibrium Method: Fundamentals and Methods presents basic principles for the safe design of constructed or natural earth slopes. The limit equilibrium method is the most common approach for analyzing slope stability in both two and three dimensions. This method identifies potential failure mechanisms and derives factors of safety for a particular geotechnical situation. It is an appropriate choice for assessing the stability of retaining walls, shallow and deep foundations, earth and rock dams, surface mining sites, and potential landslides.The fundamentals of slope stability encompass slope movements and methods for stability analysis, mechanics of slope failure and factors of safety, laboratory and field methods to determine the shear strength of soils, estimation of phreatic surfaces, and remedial measures for correcting slides. Methods of stability analysis cover simple formulas for determining the factor of safety for plane failures, stability charts, methods of slices for two-dimensional analysis, three-dimensional analysis techniques, and reliability of slope design. An appendix provides a preview of a companion product, LEAME Software and Users Manual: Analyzing Slope Stability by the Limit Equilibrium Method, a computer program for performing the slope stability analysis presented in this work.The clear presentation of the principles of slope stability analysis ensures that this work will be a frequently consulted reference for practicing engineers. The wealth of worked examples and problem sets make this a suitable textbook for senior and graduate students in soil mechanics and geotechnical engineering.

It is divided into three parts, the first of which discusses the failure mode and fundamental equation of soil mass. The second part addresses the solution methods for limit analysis, including the characteristic line method, stress field method, limit equilibrium method, virtual work equation-based generalized limit equilibrium method and generalized limit equilibrium method for the surface failure mode. Lastly, the third part examines the application of the limit analysis theory to soil mass.

Ce.A.S. s.r.l. ParatiePlus v20 [Size: 179 MB] ... In Italy as well as in many Countries worldwide, several designers rely on Paratie Plus in their retaining wall projects. For example, in the construction of the High Speed Trains guyed bridge over Po River near Piacenza, several cofferdams and other waterfront structures had been designed by our engineers using past versions of Paratie Plus. More recently, thank to the same design tool, other Italian engineering firms, have designed the temporary cofferdams for all river crossings along the new high speed train line linking Milano to Brescia. Stemming from a cooperation, since 1985, with professor Roberto Nova from Politecnico di Milano, Paratie Plus is a non linear analysis program conceived to model the soil-structure interaction of a flexible retaining wall, by means of the popular subgrade reaction method, a simple yet widely accepted approach in current design practice as well as by most of design standard worldwide, including Eurocodes.

Thanks to its effectiveness, Paratie Plus is a simple yet accurate retaining wall design tool. In most cases, a Paratie Plus analysis can be sufficient to completely define a wall design. However, even in very complex situations, Paratie Plus may provide valuable design information, at least in the preliminary design stages: if required, selected final layout will be more thoroughly analyzed, with more advance but complex programs such as FLAC. Since 2009, Paratie Plus evolved towards an integrated design environment, which offers several additional analysis options, including slope stability analysis and 2D seepage analysis. Some of the most relevant Paratie Plus features, which are hardly found in competitor tools on the market, are listed here: a rigorous soil model formulation within modern Soil Mechanics framework; a special constitutive model for clays in both drained and undrained conditions, based on critical state concepts; a realistic construction stage modelling, even for quite complex sequences; a general seepage scheme for layered soils; external loadings and interaction with nearby foundations modelling; in any construction stage, support and loading layout can be modified arbitrarily ( special non linear supports, prestressed ground anchors, struts, slabs and other features are allowed); two facing walls can be modelled thus allowing a coupled analysis of a sheetpile and its anchoring wall; a pseudo-static seismic procedure is included, based on a well documented proprietary algorithm; a GUI interface including, among many other features, a complete set of online correlations to assist the Users in selecting appropriate soil parameters based on most common in situ or lab tests; a linkage with the modern Limit Stated design methods, according to Eurocodes 7 and 8 as well as to NTC, EC2 , EC3 , AISC and ACI, for structural checks.
