摘要
以调整后省道S339恩施大峡谷旅游公路主线组成部分,景阳镇水井湾路段滑坡为例。在研究区地质勘查资料的基础上,对滑坡的破坏机理及主要影响因素进行分析,确定了该段滑坡滑动模式。分别采用模糊数学法和极限平衡法对滑坡的稳定性进行计算。最终准确的对该路段进行稳定性分析,得出该路段滑坡处于不稳定状态,必须对进行及时治理确保公路安全。
Taking the landslide in section of Shuijingwan highway , Jingyang town for example , and the section of highway which is the component of the main line of Enshi grand canyon tourist road after the provincial highway S 339 adjustment .Based on the geological exploration data in this area , the failure mechanism and main influence factors of landslide are analysed ,the sliding mode of this landslide is de-termined .The fuzzy mathematics method and limit equilibrium method are used to calculate the landslide stability.Finally,through the accurate stability analysis to this road ,the result shows the landslide in this road is unstable ,it must be governed timely ,in order to ensure the road safety .
