摘　　要：针对强降雨条件下某公路路基出现边坡沉降、局部滑塌等问题,通过分析滑塌机理,讨论了引发边坡发生沉降、滑塌的诱因,为边坡治理提供了理论依据。根据不同降雨历时与边坡稳定性安全系数的关系,讨论了边坡破坏过程,进一步判断了边坡失稳阶段,提出了基于滑塌诱因及失稳阶段的路基边坡综合防治方案,并进行了技术经济对比,对于类似路基边坡失稳防治有一定参考价值。In view of the slop subsidence,local collaplse of the roadbed of a highway under the conditions of hevay rainfall,through the analysis of slope sliding mechanism,the causes of subsidence,collapse of the roadbed is discussed,so as to provide theoretical basis for slop governance.According to the relationship between difference rainfall duration and safety coefficience of slope stability,the slope destruction process is analyzed,and the slope instability stage is determined,the integrated governance scheme based on slope sliding and instability stage is proposed,besides that,the technical economic comparison of the governance scheme is done,so as to provide reliable reference for the treatment of slope instability of roadbed.
