EARTH PRESSURES UNDER GENERAL WALL MOVEMENTS

In this paper, the finite element method is used to investigate the variation of horizontal earth pressure behind a rigid retaining wall for two categories of wall movements: (1) rotation about a point below its base (RBT mode); and (2) rotation about a point above its top (RTT mode). Triaxial tests and direct shear tests have been conducted to determine the hyperbolic parameters employed in the analyses. Numerical findings are compared with experimental results and traditional theories, and good agreements have been achieved. It is found that the mode of wall movement has a significant effect on the generation of earth pressure. For a wall under translational movement (T mode), the intensity and distribution of active earth pressure are in good agreement with Coulomb's solution. The RT (rotation about top), RB (rotation about base) and T modes are the three limiting movement modes that could occur to a rigid wall. (A)
