摘要
块体理论是近十几年来发展和完善起来的一种适合于裂隙岩体稳定性分析的行之有效的工程方法。裂隙岩体中硐室周围岩体滑落与岩体弱面分布及其力学性质密切相关,其滑移方式对于硐室维护具有重要意义。本文运用所建立的块体理论赤平解析法分析了某矿卷扬机硐室的稳定性,确定了失稳的块体,并指出可采用锚杆加固的措施。
Block Theory,which is developed in recent ten years and more,is an effective and reliable method for jointed rock mass stability analysis. The sliding of jointed rock mass surrounding a cave is correlative with the distribution and mechanical character of rock joint,and the sliding pattern is also important for the maintenance of a cave. Based on the established stereoanalytic method for Block Theory,the stability of a cave for winding engine in a mine is analyzed. Moreover,the movable blocks are determined by this method and effective measures are also suggested for reinforcement.
