Abstract

Abstract

The finite element method was used to simulate diversion canal slopes. The calculated displacement values and soil material mechanical parameter values were substituted into the input layer and output layer of the RBF neural network for training. The nonlinear relation between material parameters of multi-layer soils and displacement was obtained, and an intelligent inversion model of material parameters was established. According to monitoring displacement values at different times, the corresponding soil mechanical parameters were obtained by inversion analysis, and the parameters were used for finite element analysis to verify the accuracy of the inversion model. Combined with the inversion results, the safety factor of stability for diversion canal slopes at any time was calculated by the strength reduction method of finite elements, and the dynamic change law of slope stability was studied.
