摘　　要：本文以广东某边坡为例,使用Midas GTS NX分析了天然状态、暴雨作用和地震作用下的格构梁联合锚杆加固的土质边坡稳定性。分析结果表明加固边坡在暴雨作用和地震作用下为欠稳定状态。典型边坡剖面1在极限状态下的潜在滑移面位于第一级边坡底部,滑移面深度超过锚杆深度,实际的滑坡破坏特征与计算结果吻合。典型边坡剖面2的潜在滑移面位于第三级边坡顶部。研究成果为该边坡加固处理、监测提供依据,也为类似的边坡支护工程提供施工、设计经验。Taking a slope in Guangdong Province as an example,this paper uses Midas GTS NX to analyze the stability of a soil slope strengthened by lattice beam and anchor rod under natural state,rainstorm and earthquake.The results show that the slope is under stable under the action of rainstorm and earthquake.The potential sliding surface of typical slope profile 1 in the ultimate state was located at the bottom of the first level slope,and the depth of the sliding surface exceeded the depth of the anchor rod.The actual landslide failure characteristics are consistent with the calculation results.The potential sliding surface of typical slope profile 2 was located at the top of the third level slope.The results provide a reference for the reinforcement and monitoring of the slope,as well as construction and design experience for similar slope support projects.
