摘要
怎样利用岩体结构面与洞室开挖面相互切割形成岩石块体是大型地下洞室围岩块体稳定分析的关键技术之一。文章介绍利用ANSYS的面、体运算功能计算块体体积,并用接触单元模拟结构面,分析块体稳定性,具有较大的推广应用性。
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.
