TL;DR: In this article, the basic concepts and elementary mechanical principles of the limit equilibrium procedure for stability analysis are reviewed, and a limit equilibrium method is presented (with examples) for computing the internal stresses and the average factor of safety of slopes, using shear surfaces of any shape.
Abstract: The basic concepts and elementary mechanical principles of the limit equilibrium procedure for stability analysis are reviewed, and a limit equilibrium method is presented (with examples) for computing the internal stresses and the average factor of safety of slopes, using shear surfaces of any shape. The general applicability of the proposed method for solving slope stability, earth pressure, and bearing capacity problems is illustrated. Only plane strain or axisymmetrical stress conditions are considered. The axisymmetric case is used only for interpretation of the results of triaxial tests. Classical knowledge about equilibrium stresses in soil elements are reviewed, and principles and formulas describing 2-dimensional failure conditions for ideal soils are summarized. The principles of stress-vector curves are discussed, and their application to the interpretation of shear tests on soil samples is illustrated. The shape and location of classical failure surfaces and the corresponding state of stress is derived, and the differences between ideal plastic and ideal brittle failure is demonstrated. The paper also illustrates the application of limit equilibrium principles in obtaining information about the stress conditions at limit equilibrium and the shape of the shear surface corresponding to minimum safety factor. The generalized procedure of slices is described which can be used to: solve stability problems for irregular topography, and layered soils of different shear strengths, using shear surfaces of any arbitrary shape; explore a statically reasonable state of stress both along the shear surface itself and within the body of soil located above that surface; and unify the treatment of such categories of soil stability problems as earth pressure, bearing capacity, and slope stability.

TL;DR: In this paper, the authors used the quasi-static Mononobe-Okabe analysis for the prediction of earthquake dynamic forces on a gravity retaining wall, and showed that wall inertia effects are of the same order as the dynamic soil thrust.
Abstract: First, the paper shows that in order to use the quasi-static Mononobe-Okabe analysis for the prediction of earthquake dynamic forces on a gravity retaining wall, wall inertia effects must be included. Second, a design procedure is developed in which the designer chooses an acceptable level of wall displacement: he then computes the design wall weight which will restrict displacement in an earthquake to the predetermined level. Wall inertia effects are shown to be of the same order as the dynamic soil thrust, and to be sensitive to vertical acceleration and to base and wall friction. Design recommendations are given which relate to proposed American provisions for seismic zoning.

TL;DR: In this paper, the authors present both theoretical and practical knowledge of soil mechanics in engineering, and discuss most suitable methods and types of equipment for fills, excavations, and foundations.
Abstract: This Wiley classic presents both theoretical and practical knowledge of soil mechanics in engineering. Written by Karl Terzaghi, universally recognized as ``the father of geotechnical engineering,`` it has long been the standard in the field. It offers a fundamental understanding of how to determine and use soil properties needed for design and construction; points out appropriate nature and benefits of exploration and soil tests under various conditions; and discusses most suitable methods and types of equipment for fills, excavations, and foundations. It also features expanded coverage of vibration problems, mechanics of drainage, passive earth pressure, and consolidation. This book contains information on the following. Part 1: physical properties of soils; index properties of soils; soil exploration; and hydraulic and mechanical properties of soils. Part 2: theoretical soil mechanics; hydraulics of soils; plastic equilibrium in soils; and settlement and contact pressure. Part 3: problems of design and construction; ground improvement; earth pressure and stability of slopes; foundations; settlement due to extraneous causes; and dams and dam foundations.
