巫山收费站滑坡成因机制与整治措施

Cause Mechanism and Regulation Measures of Landslides in Wushan Toll Station

巫山收费站滑坡为一老滑坡体,公路线路主要以路堑的形式自滑坡中部穿过,导致老滑坡中级滑块发生变形破坏,虽经多次治理,均以失败告终,归根结底是因为缺乏对滑坡成因机制及滑动面判识的准确认识,导致整治工程措施缺乏针对性,难以有效根治。再次进场整治时,采用了综合勘察手段,经过深入研究,查清了滑坡坡体结构、成因机制,提出了有针对性的综合整治措施,并顺利实施,据相关监测成果及回访调查,整治工程成效显著。

The landslide in Wushan toll station is an old landslide body,and the road lines are mainly through the form of cutting in the form of the middle of the landslide,resulting in the deformation and destruction of the intermediate slide block of the old landslide. Although it has failed after many times of treatment,it is due to the lack of accurate understanding of the mechanism of landslide cause and the recognition of sliding surface. Engineering measures are lack of pertinence and are hard to cure effectively. Once again,comprehensive survey means are adopted. After in-depth study,the structure and mechanism of landslide slope are found out,and the comprehensive measures are put forward and implemented smoothly. According to the related monitoring results and return visits,the effectiveness of the renovation project is remarkable.
