Using a unified approach to address a medley of engineering and construction problems, Slope Stability Analysis and Stabilization: New Methods and Insight, Second Edition provides helpful practical advice and design resources for the practicing engineer. This text examines a range of current methods for the analysis and design of slopes, and details the limitations of both limit equilibrium and the finite element method in the assessment of the stability of a slope. It also introduces a variety of alternative approaches for overcoming numerical non-convergence and the location of critical failure surfaces in two-dimensional and three-dimensional cases.
What’s New in the Second Edition:
This latest edition builds on the concepts of the first edition and covers the case studies involved in slope stability analysis in greater detail. The book adds a chapter on the procedures involved in performing limit equilibrium analysis, as well as a chapter on the design and construction practice in Hong Kong. It includes more examples and illustrations on the distinct element of slope, the relation between limit equilibrium and plasticity theory, the fundamental connections between slope stability analysis and the bearing capacity problem, as well as the stability of the three-dimensional slope under patch load conditions.
Addresses new concepts in three-dimensional stability analysis, finite element analysis, and the extension of slope stability problems to lateral earth pressure problems
Offers a unified approach to engineering and construction problems, including slope stability, bearing capacity, and earth pressure behind retaining structures
Emphasizes how to translate the conceptual design conceived in the design office into physical implementation on site in a holistic way
Discusses problems that were discovered during the development of associated computer programs
This text assesses the fundamental assumptions and limitations of stability analysis methods and computer modelling, and benefits students taking an elective course on slope stability, as well as geotechnical engineering professionals specializing in slope stability
Dr. YM Cheng has an interest in research work in slope stability: unification of 2D methods, location of critical 2D failure surfaces, 3D slope stability analysis, location of critical 3D failure surfaces, development of slope stability software SLOPE2000 and SLOPE3D, unification of lateral earth pressure and slope stability problems, convergence problems in slope stability analysis, field tests of steel, GFRP, CFRP bars and tubes soil nails in Hong Kong, numerical modelling of soil nail pull out tests, finite element analysis of slope stability, and distinct element analysis of slope stability analysis.
