摘要
利用快速拉格朗日有限差分程序(FLAC3D),对不同空间布置的地下硐室群围岩稳定性进行数值分析,得出了硐周围岩剪应力、变形和塑性破坏深度随硐室间净距、硐向以及硐室群与坡表距离的变化规律,为硐室群布置方案优化提供了技术支撑。
Underground caverns with different spatial layout were analyzed by using FLAC3 Dwith its built-in Ubiquitous-Joint model and Mohr-Coulomb model. With the variation of clear distance, axes direction and distance to the surface of slope, the change law of shear stress, deformation and distribution of plastic zone were summarized, which provide a technical support of the optimal layout of underground powerhouse.
