摘要
本文简述了围岩塑性圈的基本理论,并采用有限元计算软件,对地下洞室开挖后形成的塑性圈进行了数值模拟计算。通过对塑性屈服单元进行参数优化,较真实地模拟了地下洞室开挖后围岩塑性圈的影响。
The paper introduces the basic theory of adjoining rock plastic circle conductes the numerical simulation calculation of plastic circle after excavation of underground cavern with finite element software.Through optimization of plastic yield element parameter,The influence of adjoining rock plastic circle is simulated true.
