| Abstract: | How to utilize the rock mass formed by mutual cutting between the structural plane of rock mass and the excavated plane of cavern is one of key technologies on analysis of stability of blocks of surrounding rock of large underground caverns.In this paper,calculation of the block volume by application of calculation functions of ANSYS planes and bodies is introduced.Furthermore,contact element is applied to simulate the structural plane so as to analyze stability of block.This calculating and analyzing method is with application to be promoted largely. |
