摘要

从正断层区域的应力状态出发,对隧道开挖地质灾害类型、灾害机制及防治对策进行了研究,定义了正断层区域节理岩体中隧道开挖的灾害类型为结构型破坏并对其进行分类;利用块体理论的思想方法研究隧道破坏过程,将岩块向临空面滑移分为3种形式:塌落、沿单面滑移和沿两面滑移,并系统研究3种滑移的力学机制;隧道支护以工程岩体分类为基础,提出隧道支护系统的建立应以主动支护与被动支护相结合为主导思想。
From the stress status of down fault region the type of disaster of tunnel excavating in jointed rock mass is de-fined as structural disaster;main contro1 factors,disaster mechanism and control strategy in tunnel excavating are studied systematically in this thesis By means of the Block Theory,the tunnel destroy process can be studied,in which the block slip to spacing of tunnel can be described as three types: collapse\slip along single plane and slip along two planes,addi-tionally the mechanics theory of these types of slip is Studied systematically on the basis of engineering rock mass classifi-cations,the support system is advanced that the active support and passive one may be combined.
