暴雨诱发路堑边坡滑移成因分析及治理方案设计

Cause Analysis and Treatment Scheme Design of Cutting Slope Slippage Induced by Rainstorm

某高速公路一路堑边坡在经历持续强降雨天气之后,出现了大范围滑动变形,严重影响了工程安全和施工进度。根据该路堑边坡的特征和稳定性分析结果,研究其滑塌形成机理,提出相应的处理方案,历经几次降雨后,坡顶及坡面未见新的裂缝发育,整体稳定,达到了预期目标。

A large range of sliding deformation of a cutting slope of an expressway is found after continuous heavy rainfall,which seriously affects the project safety and construction progress.According to the characteristics and stability analysis results of the cutting slope,the formation mechanism of its collapse is studied,and the corresponding treatment scheme is put forward.After several rainfalls,no new crack development is found on the slope top and slope surface,and the overall stability is realized,achieving the expected goal.
