摘要
采用极限平衡法对遵义市海龙囤龙虎大道侧的W5滑移式危岩体进行稳定性分析,得出不同工况下的稳定系数,并依据规范判断其稳定性。运用geo-studio数值模拟软件对W5滑移式危岩体的稳定性进行模拟分析,基于应力场和位移场的分析表明,该滑移式危岩处于欠稳定状态。根据相关规范,对其进行锚固灌浆支护设计,并运用理正软件验算支护后W5危岩体的稳定性。
Through analysis and calculation with limit equilibrium method on W5 sliding dangerous rock mass at both sides of Longhu Avenue in Hailong Village in Zunyi,the coefficient of stability of the rock mass under different loading conditions is obtained and its stability is judged according to the specification.This paper applies the numerical simulation software of Geo-studio to analyze the stability of W5 sliding dangerous rock mass,the results which are based on the analysis of the stress field and displacement field show that this sliding dangerous rock is understable.According to the relevant specification,the anchorage grouting support design is carried out and the stability of W5 dangerous rock mass is checked using Lizheng software.
