HYDRALIC ANALYSIS OF POST-FAILURE BEHAVIOUR DUE TO BANK SLOPE LANDSLIDE

摘要：

Hazard assessment induced by landslides is made difficult by unpredictable post-failure behaviour. According to studies engineering, the hydralic analysis of post-failure behavior is estimated. The empirical formula was employed to evaluate surge wave. The numerical hydraulics (Delft 3D) was used to quantify the harm of maximum water swelling height; Based on the theory and basic conception of closure riprap grain size, the hazard of the block rock carriying by flow is measured. The minimum flow section of diversion tunnel is estimated.Some useful rules and conclusions are obtained through the simulation, which afford a basis for the hydralic analysis.
