摘　　要：某高速公路枢纽由于匝道桥梁的布设,滑坡前缘现有村村通公路需进行改路,靠山体改移,改路后路线切割滑坡前缘对坡脚产生扰动,影响滑坡的稳定性。文章主要通过不平衡推力传递法对改路后滑坡稳定性进行分析评价,并提出合理的处理措施建议。Due to the layout of ramp bridges in a highway hub,the existing village-to-village highway at the front edge of the landslide needs to be changed,and the mountain is changed.After the change,the cutting of the front edge of the landslide causes disturbance to the slope toe and affects the stability of the landslide.This paper mainly analyzes and evaluates the stability of landslide after road modification by unbalanced thrust transfer method,and puts forward reasonable suggestions for treatment measures.

关 键 词：改路 滑坡 稳定性分析 措施建议
