Elements of soil mechanics for civil and mining engineers. 5th edition

Abstract: The book presents in a 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 changes in technology and professional requirements, and in addition, the text now includes an introduction to critical state theory. The subject is discussed in the following chapters: 1) classification and identification properties of soil; 2) soil water, permeability and flow; 3) other solutions to seepage problems; 4) shear strength of soils; 5) stability of slopes; 6) earth pressure; 7) elements of stress analysis; 8) bearing capacity of soils; 9) foundation settlement, soil compression; 10) the 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.

Determination of active earth pressure on rigid retaining wall considering arching effect in cohesive backfill soil

Abstract: A new simplified method is proposed to compute the active earth pressure acting on the backface of a rigid retaining wall undergoing horizontal translation. The effect of soil arching for cohesive backfill soil and friction mobilized along the wall–soil interface was considered. Analytical expressions to determine the slip surface angle and the coefficient of active earth pressure were obtained using the limit-equilibrium approach. These expressions were used for the horizontal flat-element method to obtain theoretical formulas for the active earth pressure, active thrust, and its point of application. Additionally, an implicit solution was derived for the depth of the tension crack in the backfill. A parametric study was undertaken to assess the effects of cohesion, unit weight, friction angle, surcharge pressure, and wall–soil friction angle on the active earth pressure, as well as the effects of the friction angle of backfill soil and wall–soil friction angle on the slip surface angle. The resu...

Strength of reinforced soil

Abstract: Two theoretical models for the behaviour of reinforced soil at failure are proposed. Both refer to a horizontally reinforced soil mass which fails by expanding in the direction of the reinforcement. In the first model reinforcement is seen as producing an intrinsic prestress, or lateral restraint, when failure conditions are approached. Second model reinforcement is assumed to induce horizontal and vertical shear stresses into the originally geostatic conditions. If the lateral prestress or induced shear stress has a constant value related to the strength of the reinforcement, a cohesion intercept results. If they are proportional to the initial vertical stress, an increase in the angle of friction results. These conditions correspond to failure by rupture of the reinforcement and failure by slippage between the reinforcement and the soil. Triaxial test results presented support the concept of friction angle increase while the cohesion-effect has been recognised for some time. The concept of reinforcing efficiency is introduced for interpreting the test results. Reference is made to the Reinforced Earth Technique which takes advantage of the reinforcing effect although standard design procedures usually assume anchored wall elements subjected to active earth pressure.
