本文介绍采用岩石锚杆加固岩石垂直壁,形成岩石锚喷直壁承载体系的原理。运用摩尔-库伦破坏准则,提出了有外加荷载的岩石垂直壁的稳定分析方法。按照楔体滑动模式,提出了岩石锚喷直壁的计算公式及设计方法。 This paper describes the principle of using rock bolts to reinforce the vertical walls of rocks to form a rock bolted and straight wall bearing system. Using the Mohr-Coulomb failure criterion, a stability analysis method for vertical walls of rocks with external loads was proposed. According to the wedge sliding mode, the formulas and design methods for the straight wall of rock bolting and spraying are proposed.
