Abstract
Different numerical approaches for the analysis of earthquake triggered landslides are studied. Improved simplified models are developed and their performance for evaluating the response of natural slopes subjected to earthquakes is studied. Using more sophisticated numerical techniques the influence of several factors such as the hydro mechanical behavior assumptions, 1D vs. 2D geometry, and the input motion are assessed. 2D computations have shown that the kinematics of the slope motion is largely affected by the geometry of the slope. As far as the soil behavior is concerned, the results indicate that introduction of progressive yielding in the soil model provides larger displacement, progressive pore-pressure generation and more diffuse deformation. For the input motion, the number of peaks and their amplitudes have been identified as being the mains factors for irreversible displacements.
