Inversion analysis of mechanical parameters of slope rock mass in Baiyunebo open pit iron mine

摘要：

An inversion analysis model for mechanical parameters of open pit slope rocks was established. Based on orthogonal design, finite element method and RBF neural network. According to orthogonal design, the value levels of the mechanical parameters were chosen, and simulation schemes were arranged; the related analytical samples for neural network were given by calculations with MIDAS/GTS finite element software; RBF neural network was trained; the mechanical parameters of open pit slope were inversely analyzed by well-trained RBF neural network using the actual landside body mechanical parameters of Baiyunebo iron mine Finally the mechanical parameters of the open pit slope were obtained. The error between the inverse analysis results and the theoretical ones is much little and meets the demand of precision. The results provide a reasonable basic data for analyzing the stability of mine slope.
