某市政道路滑坡稳定性分析及治理措施研究

通过现场踏勘与地质勘察，分析了某市政道路滑坡的物质结构特征及变形原因。运用Geo-Slope之Slope/W软件建立滑坡地质力学模型，计算结果表明在正常工况下该滑坡欠稳定，在暴雨工况下该滑坡不稳定，亟需工程治理。根据滑坡特征，设计并验算了桩板墙支挡方案，计算结果满足规范要求。经过工后监测，该滑坡变形小于设计要求，表明该滑坡体得到有效治理。

Stability Analysis and Control Measures of Landslide along a Municipal Road

The material structure characteristics and deformation causes of a municipal road was analyzed through on-site investigation and geological exploration. The geo-mechanical model of landslide was established with Slope/W software (Geo-Slope), and its calculation result showed that this landslide was understable in normal conditions and instable in heavy rainfall, thus required engineering improvement urgently. According to the characteristics of landslide, the sheet-pile retaining wall was designed and calculated with the result in line with the specifications. Depending on the post-construction monitoring, the deformation of landslide was below the design requirement, showing that this landslide was under valid control.
