TL;DR: In this article, a computationally efficient, analytical approach to evaluate the stress distribution across a frictional-cohesive backfill behind a rigid retaining wall under static conditions is presented, where the vertical slice method, commonly adopted in log-spiral type, limit-equilibrium earth pressure assessment methods, was further discretized into dices to capture the variation in stresses in the backfill.

TL;DR: For many years engineering practice for earth retaining structures emphasized earth pressures and their application in choosing an appropriate design and support system as discussed by the authors, and there has been an increasing use of reinforcing elements, either by incremental burial to create reinforced soils or by systematic in situ installation to produce soil nailing.
Abstract: For many years engineering practice for earth retaining structures emphasized earth pressures and their application in choosing an appropriate design and support system. In the last 25 years there has been a dramatic growth in new construction technologies and products for retaining soil. In particular there has been increasing use of reinforcing elements, either by incremental burial to create reinforced soils or by systematic in situ installation to produce soil nailing. Rapid developments in polymer manufacturing have led to a wide range of polymeric products (geosyn-thetics) (see Chapter 7). These materials are now routinely used to reinforce the soil in retaining wall and slope applications, and to control soil drainage. Reinforced soils and soil nailing have changed the ways built-up and in situ walls are constructed by providing economically attractive alternatives to conventional methods. The use of these products in reinforced soil applications has led to many different earth retention systems.

TL;DR: In this paper, a new formulation is proposed for determination of active earth pressure, angle of failure wedge and application point of resultant force for inclined walls, assuming the pseudo-static seismic coefficient to be valid in earthquake conditions.
Abstract: Inclined retaining walls with slopes less than perpendicular are appropriate candidates in several engineering problems. Yet, to the knowledge of authors, only a few analytical solution for calculation of active earth pressure on such walls, which will be usually smaller than the same pressure on vertical ones, has been presented neither in research papers nor in design codes. Considering limit equilibrium concept in current research, a new formulation is proposed for determination of active earth pressure, angle of failure wedge and application point of resultant force for inclined walls. Necessary parameters are extracted assuming the pseudo-static seismic coefficient to be valid in earthquake conditions. Moreover, based on Horizontal Slices Method (HSM) a new formulation is obtained for determining the characteristics of inclined walls in granular and or frictional cohesive soils. Findings of present analysis are then compared with results from other available methods in similar conditions and this way, the validity of proposed methods has been proved. Finally according to the results of this research, a simplified relation for considering the effect of slope in reduction of active earth pressure and change in failure wedge in inclined retaining walls has been proposed.

TL;DR: The application of soil mechanics to the field of civil engineering can be found in this article, where a number of worked examples are presented in concise form, including a large amount of new material dealing with the moisture condition apparatus, site investigation, and ground improvement techniques.
Abstract: This book presents in concise form the applications of soil mechanics to the field of civil engineering and also includes a number of worked examples. The latest edition of the book has been revised to include a large amount of new material dealing with the moisture condition apparatus, site investigation, and ground improvement techniques. The topics of lateral soil pressure and earth retaining structures have been expanded into two separate chapters. The subject is discussed in the following chapters: 1) classification and identification properties of soils; 2) soil water, permeability and flow; 3) shear strength of soils; 4) elements of stress analysis; 5) stability of slopes; 6) lateral earth pressure; 7) earth retaining structures; 8) bearing capacity of soils; 9) foundation, settlement, soil compression; 10) rate of foundation settlement; 11) compaction and soil mechanics aspects of highway design; 12) soil suction and partial saturation; 13) critical state theory; and 14) site investigation and ground improvement.
