Complex 3D landslide simulation

摘要

A numerical model for prediction of slope movements based on a multidisciplinary approach is presented. Detailed geophysical investigations have resulted in creating a geophysical-geological structure model of high-resolution for the rock mass. The paper documents the ability of a numerical model based on a complex constitutive law with hydro-mechanical coupling to provide excellent representation of the underlying physical process of creep and short-termed sliding movements. Based on a plausible and calibrated physical model, reliable predictions for slope behaviour under different precipitation scenarios and water-reservoir regimes were made. The application of the numerical model has provided valuable insight into the hydromechanical mechanism of slope movement. The application of the model has answered questions concerning the conditions under which slope failure can be expected, the expected slope displacements and velocities under different precipitation scenarios, and the most sensitive locations of measuring devices used for slope observation.
