Abstract: Many naturally deposited clay soils are anisotropic. In such deposits, the undrained shear strength of the clay is different in the active and passive conditions. This project studies the influence of the strength anisotropy of the clay on the stability of slopes using an advanced soil stress-strain model. Extensive studies will be carried out using the plane strain Finite Element Software PLAXIS2D. Analyses were carried out for a 10m deep slope in a homogeneous clay soil. The soil parameters that were studied included the slope angle, the passive to active shear strength ratio and the depth between original ground surface and bedrock. Results obtained show that these parameters did significantly affect the factor of safety of the slope. Higher passive to active shear strength ratio and shallower depth between original ground surface and bedrock resulted in higher factor of safety. Generally, the factor of safety decreased with increasing slope angle. Based on the analyses, a series of stability charts were developed to assess the factor of safety.
