摘要
在地下洞室开挖过程中,由结构面切割形成的不稳定块体是影响坚硬岩体稳定性的主要因素之一。依据块体理论,利用Unwedge程序对一条正在施工的地下洞室进行块体稳定性分析,得出块体在系统支护前后的安全系数,为工程的支护工作提供参考和建议。
In the excavation of underground caverns, one of the main factors affecting the stability of thehard rock is unstable block formed by the structural surface. Based on the basic concepts and principles of block theory, using Unwedge program the stability of block is analysed in an underground cavern which is under ex- cavation. The safety factor of block is got before and after the system supporting and providing reference and suggestions to the supporting work of the project.
