| 摘 要： | 采用三维有限差分法对某水电站的地下厂房分级开挖过程进行仿真模拟，研究了采用喷锚支护和无支护条件下围岩应力场、位移场及破坏区的分布规律。结果表明：对围岩采取喷锚支护措施将优化围岩应力分布、限制围岩变形及破坏区分布，有效提高开挖过程中的围岩稳定性。

| Abstract: | Three -dimension finite difference method is applied to model staged excavation process of underground powerhouse in Tizidong Hydropower Station. And distribution laws of stress, deformation and zones are studied for excavating surrounding rock with and without support measurements. The resuits showed that support can optimize stress distribution, confine ranges of deformations and damage zones, and improve stability of surrounding rock during excavation process. |
