Research on Reservoir Slope Stability and Risk Prediction Based on Fluid Structure Coupling
The stability analysis of reservoir slopes is an important method for predicting the settlement,deformation,and sliding of strata caused by various loads and environmental conditions.The stability analysis of slopes in reservoirs is crucial for determining the safety of dams.The research aims to study the slope stability of dams and the risk prediction of reservoir slopes.Based on Yele Hydropower Station in Sichuan Nanya River,a three-dimensional fluid structure coupling simulation of reservoir slope stability was conducted using Comsol-Multiphysics software.The seepage and collapse characteristics of reservoir dam slopes under pore water pressure were explored,and the relationship between factor of safety(FOS)of reservoir dams and slope collapse displacement was obtained,providing reference for risk prevention and control of reservoir dam slopes and strengthening dam safety design.
