摘要
根据块体理论的矢量运算方法,将隧道围岩稳定性问题转化为寻找和分析关键块体的问题,并以某公路隧道为例将其应用到工程实践中,通过几何分析和结构面的物理力学性质,确定了失稳的块体,指出可采用锚杆加固的措施。
Based on vector computational method of block theory, the problem of tunnel surrounding rock stability is transformed to search and analyse key block. And this method is applied to a road tunnel engineering. According to geometrical analysis and physical and mechanical prop erties of structural plane, the movable blocks are determined and effective measures are also suggested for reinforcement.
