摘要:
隧道开挖后,侧墙上方将出现应力集中现象.为解决深埋隧道底板变形难以支护的工程问题,本文以松山深埋隧道为工程背景,借助极限平衡理论分析了隧道侧墙岩体的极限平衡宽度及其底板极限承载力.结果表明:当底板极限承载力小于隧道侧墙峰值集中应力时,隧道底板将出现剪切滑动.基于滑移线场模型讨论了侧墙集中压力作用下底板岩体的最大破坏深度及其位置.在此基础上,研究了松山隧道底板及墙角锚杆支护的关键参数,取得了良好的支护效果,研究成果具有一定的理论意义和工程应用价值.
Abstract:
Stress concentration will occur above the side wall after tunnel excavation. In order to solve the engineering problem that the floor anchor is difficult to support due to the deformation of the deep-buried tunnel floor, this paper, taking Songshan deep-buried tunnel as the engineering background, analyzes the ultimate equilibrium width of tunnel side wall rock mass and the ultimate bearing capacity of its floor by means of the limit equilibrium theory. The results show that when the ultimate bearing capacity of the floor is less than the peak concentrated stress of tunnel side wall, the shear sliding of the tunnel floor will occur. Based on the slip line field model, the maximum failure depth and location of the floor rock mass under the concentrated pressure of the side wall are discussed. On this basis, the key parameters of Songshan Tunnel floor and corner anchor support are studied, and good support effect is achieved. The research results have certain theoretical significance and engineering application value.
