摘　　要：高速公路路堑施工对斜坡力学平衡的破坏,是引起老滑坡复活的重要诱因。为科学应对多滑带路堑滑坡治理难题,以文麻高速公路多滑带路堑滑坡为背景,系统分析滑坡发育特征与各滑带形成原因。针对多滑带特征,提出了综合排水+强支挡的综合治理技术。由渗流与稳定性分析、变形监测数据可知,提出的综合治理措施治理效果良好,具有可行性。The destruction of the slope mechanical balance by highway cutting construction is an important cause for the revival of old landslides.In order to scientifically deal with the harnessing problem of multi-slip cutting landslide,taking the multi-slip cutting landslide of the Wenshan to Malipo highway as the background,development characteristics of the landslide and the formation reason of the multi-slips were analyzed.Aiming at the characteristics of multi-slips,a comprehensive treatment technology of comprehensive drainage+strong support is proposed.From the analysis of seepage and stability,as well as deformation monitoring data,the proposed comprehensive treatment measures have good effect and are feasible.
