Intelligent Identification of High Rock-Filled Embankment Elastic-Plastic Model Parameters and Application

摘要

Based on the elastic-plastic model and the orthogonal design table, the ANSYS finite element method was combined with the BP neural network to establishe high rock-filled embankment constitutive model parameters inverse analysis method. According to the field monitoring settlement data of Hurongxi highway, the elastic-plastic model parameters of high rock-filled embankment were identified and the inversion parameters were used to calculate and analyze. Compared with the measured settlement, it was found that the calculated settlement were in good agreement with it. Therefore, the method is higher reliability.
