Active Earth Pressure with Linear and Nonlinear Failure Criteria
Geotechnical and Geological Engineering, 2017Most conventional calculation methods of active earth pressure behind a retaining wall are mainly based on the linear Mohr–Coulomb failure criterion. However, numerous experimental data indicate that various kinds of soils obey the nonlinear failure criterion.

Active Earth Pressure Behind Retaining Walls
Journal of Geotechnical Engineering, 1985A simple and realistic analytical procedure is described to estimate the eveloped lateral earth pressure behind the rigid retaining wall with cohesionless backfill soil experiencing outward tilt about the base. Included are various stages of wall tilt starting from an initial active state to a full active state. The initial active state is defined as a

Dynamic active earth pressure on cantilever retaining walls
Computers and Geotechnics, 2011Abstract In normal practice, the active earth pressure on cantilever retaining wall is evaluated with different procedures relating to an ideal vertical plane passing through the heel of the wall. If the wall presents a long heel, failure planes do not interfere with the vertical stem, so that the limit Rankine conditions can develop freely in the ...

Active Earth Pressure on Walls with Base Projection
Journal of Geotechnical Engineering, 1990This paper presents the effect of base projection on the active earth pressure. It was found that the failure wedge is bounded by two surfaces, one of them intersecting into the soil and the ground surface and the other one intersecting the wall. The inclination of the first surface is independent of the wall friction and the length of base projection.

Effects of Strain Localization on Seismic Active Earth Pressures
Journal of Geotechnical and Geoenvironmental Engineering, 2010An improved method based on pseudostatic and limit-equilibrium analysis is proposed for evaluating seismic (static plus dynamic) active earth pressures induced by backfill behind movable rigid retaining walls. The proposed method can take into account the effects of strain localization and postpeak shear resistance reduction in the dense backfill soil ...

Active earth pressure on retaining walls of finite length
Hydrotechnical Construction, 19761. The active earth pressure on retaining walls of finite length is considerably less than that determined by the Coulomb theory. 2. The coefficient of pressure decrease depends on the soil parameters and ratio K=B/H. When K>5 the solution approximates the Coulomb solution. 3. The slope angle of the slip plane of the soil for
