薄层复合顶板围岩破坏数值模拟分析

Numerical simulation analysis on the surrounding rock damage of thin-layer complex roof

通过数值模拟了不同侧压系数下薄层复合顶板的围岩的破坏特征,结果表明,侧压系数影响着巷道围岩的破坏。对于进一步深入理解深部岩体中巷道破坏失稳机制并采取有效的加固措施等具有重要的理论和实践意义。

The paper analyzed the surrounding rock damage characteristics of thin-layer complex roof under different lateral pressure coefficient.The result shows that the surrounding rock damage is affected by lateral pressure coefficient.The study has important theoretical and practical significant for taking effective reinforcement measures.
