Inversion Analysis of Bank Slope Geo-mechanic Parameters Based on Monitoring Data
摘要
Abstract
The displacement of bank slope is analyzed by finite element analysis software ANSYS.The displacement values of soils and the elastic modulus of corresponding soil layers are taken as the input layer and the output layer of neural network respectively.The simultaneous inversion method and the hierarchical iterative inversion method are used to carry out the inversion of elastic modulus respectively.In order to verify the accuracy of inversion results,the elastic modulus obtained by two inversion methods are analyzed by using finite element analysis.The results show that the errors between calculated displacement and measured displacement of two methods are all smaller,and the elastic modulus simulation results obtained by hierarchical iterative inversion method are better fitted with the measured displacement series.关键词
