中文摘要：

显石寨村滑坡威胁着花巴输气管线的正常运营,且坡体上堆载、工程建设活动影响强烈。为研究滑坡稳定性及其作用下管道的易损性,本文从滑坡地质背景、变形特征及形成机制入手,通过定性分析和定量评价计算,确定了滑坡的稳定性及控制因素。在此基础上,对管道的易损性做出了定量评价,并提出了相应的处理措施建议。

英文摘要：

The landslide and the engineering activities on the slope threaten the normal operation of the Hua-Ba gas pipeline. Qualitative analysis and quantitative calculation are applied to the study on the landslide stability and on its controlling factors from the perspective of geological background, deformation features and formation mechanism. A quantitative evaluation of the pipeline vulnerability is made and corresponding treatment measures are proposed.
