摘要：In order to study the valley deformation and rock mass stability of plunge pool slope at the Wudongde hydropower station. We analyzed the deformation law of valley base of site displacement monitoring. Based on the finite element method, the slope stability of different typical profiles on both banks and valley deformation is investigated. The numerical and monitoring results of deformation have a good consistency, and demonstrate that excavating and other perturbations can quicken the creep deformation of rockmass. Through deformation monitoring combined with simulation, rock mass stability analysis and evaluation are reasonable. The nonlinear large deformation of rock mass is considered, and the slope safety factor is obtained quickly. Meanwhile, it is convenient to simulate the instability state and failure process of sliding surface with any landscape and arbitrary shape as well as intuition and applicability.
