Abstract

The Random Finite Element Method has been used to investigate the influence of anisotropic spatial variability of soil shear strength on the failure probability and consequence of an idealized three-dimensional (3D) slope subjected to different lengths of static surcharge loads, to give a simplified representation of a railway embankment subjected to train loading. For each studied case, the probability of design failure has been computed as a function of the factor of safety (FoS) based on 500 realizations. The results demonstrate the combined effect of the spatial correlation of soil strength and the load distribution along the slope length on the probabilistic characteristics of the system response.
