摘要
采用工程地质决策理论,构建了地下洞室群稳定性分析工程地质系统,并以某抽水蓄能电站为依托,利用FLAC3D数值分析法,模拟计算洞室群在不同支护条件、不同开挖工况下,围岩的变形及应力变化特征。结果表明:该方法既能有效分析评价洞室围岩稳定性,又能为洞室群开挖提供动态优化设计依据。
The paper constructs the engineering geological system stability analysis of underground cavern group with the engineering geology decision theory.Taking apumped storage power station for example,the numerical simulation method of FLAC3 Dis used to simulate the influence of deformation,stress and plastic zone of surrounding rocks on their deformation under different support conditions and different excavation conditions.The results show that the method can not only effectively analyze the stability of the surrounding rocks,but also provide the dynamic optimization design basis for the excavation of the cavern.
