Abstract
The upper bound technique of limit analysis of perfect plasticity is applied to evaluate the stability of slopes induced by earthquake load. The analysis considers the following three cases : (1) homogeneous and isotropic slope, (2) homogeneous but anisotropic slope, and (3) nonhomogeneous and anisotropic slope.The computer models developed are based on the following conditions : (1) Plane strain, (2) plane and log-spiral failure surfaces, (3) pseudo-static earthquake loading, (4) uniform horizontal distribution of lateral acceleration, and (5) Coulomb criterion for failure with variable c but constant φ.
