滑坡灾害一直是重要的地质和工程问题，也是重要的影响管道安全运行的灾害。分析和挖掘其形成机理，探讨其防治措施，对管道的安全运营具有重要意义。根据兰成渝管道穿越某滑坡体的地形地貌特点，分析出该滑坡的内部因素主要是地下水丰富，多处泉眼出露；外部因素为人类工程活动的修建公路和管道，以及公路上的动荷载对灾害发育影响显著。通过在投资估算、施工可行性、环境保护以及保护管道的针对性等方面分析，本滑坡采用抗滑桩板墙，通过实践，确实达到了稳定滑坡的效果。

Landslide is an important geological and engineering problem and also a major disaster affecting the pipeline's safe operation .Therefore ,it is of significance to analyze its forming mechanism and prevention measures .Based on topographical features of a landslide mass the Lanzhou -Chengdu-Chongqing pipeline passes through ,this paper finds out that abundant underground water is the internal factor that causes the landslide and human engineering ac‐tivities such as building roads and pipelines are external factors .By investigating investment estimation ,construction feasibility ,environmental protection as well as pipeline protection ,this paper suggests that the pile-sheet retaining wall should be adopted to prevent landslide disaster .
