摘　　要：寨子坪滑坡为一岩质滑坡,公路路线以桥梁和路堑的形式从滑坡体前部穿过,施工过程中滑坡体后缘及侧面产生了明显的滑动变形。采用深孔位移监测和地质钻探相结合的综合勘察手段,查清了滑坡体的结构特征,对滑坡体的滑动面有了准确的判断;经过深入研究,分析出滑坡的成因机制,并提出了有效的整治措施。Zhaiziping landslide is a rock landslide.The highway route passes through the front of the landslide body in the form of bridges and cutting.During the construction process,the back edge and side of the landslide body have obvious sliding deformation.By means of comprehensive investigation combined with deep hole displacement monitoring and geological drilling,the structural characteristics of the landslide body are clarified,and the sliding surface of the landslide body is accurately judged.Through in-depth study,the formation mechanism of the landslide is analyzed,and effective remedial measures are put forward.
