层状围岩中地下洞室分析法

Mechanical Analysis of Rock Mass with the Stratified Structure

本文就地下工程中层状围岩的应力、位移和稳定问题,采用经典解析法、加权余量法、边界单元法和有限单元法进行对比分析,取得积极成果.

On the basis of the new concept of the stratified and platefracture structure,this paper discusses the differences of theirmechanical models used,The engineering examples show that instability and stress analysis of underground cavities,the meth-ods suggested by the authors sometimes lead to better economiceffects.
