Slope Analysis summarizes the fundamental principles of slope analysis. It explores not only the similarities but also the differences in rock slopes and soil slopes, and it presents alternative methods of analysis, new concepts, and new approaches to analysis. The book introduces both natural and man-made slopes, the nature of soils and rocks, geomorphology, geology, and the aims of slope analysis. These topics are followed by chapters about stress and strain, shear strength of rock and soils, and progressive failure of slopes. This book also presents limit equilibrium methods I and II, which are the planar failure surfaces and slip surfaces of arbitrary shape, respectively. It also includes stress analysis and slope stability, natural slope analysis, and a brief review on plasticity and shear band analysis. Before presenting its conclusions, the book discusses special aspects of slope analysis, such as earthquake analysis, pseudo-static analysis, dynamic analysis, and anisotropy, in addition to Newmark's approach.

Any undisturbed rock mass is subject to natural stresses inclu ding gravitational stresses due to the mass of the overburden and possibly tectonic stresses due to the straining of the earth's crust and remanent stresses due to past tectonism. Knowledge of the in situ stress field must be integrated into any rock engineering design along with general rock mass characteristics such as de for mability, strength, permeability and time dependent behavior. For example, the choice of optimum orientation and shape of deep underground caverns or complex underground works will be controlled by the orientation and the magnitude of the in situ stress @ield if it is necessary to minimize stress concentration problems. Long term variation of the in situ stress field may also help to evaluate the potential hazard of earthquake occurences. The magnitude and orientation of the stress field ata point within a rock mass can be measured but there is no known method by which the state of stress at a point can be accurately determined by instruments located remotely. In general, measurements are made inside boreholes, on outcrops or on the internal surfaces of under ground cavities. Most of the measuring techniques intentionally disturb the state of stress in the rock and then measure consequent strains and displacements. Measured strains or displacements are then related to the stresses through assumptions of material behavior. A common procedure is to assume that the rock mass is linearly elastic, isotropic, continuous and homogeneous.

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.
