通过长输管道沿线地质灾害调查与风险评价，统计分析得到河沟道水毁是最为发育、风险性较大的灾害类型之一，其破坏方式可划分为河沟床冲刷下切、河沟床淤积抬升和岸坡坍塌3类。依据长输管道敷设方式及其与河沟道水毁位置关系，可划分为管道穿越河沟道、管道跨越河沟道、管道顺河沟床敷设和管道顺岸坡敷设4类。重点分析不同敷设环境下长输管道河沟道水毁的危害特征，在此基础上，采用层次分析法进行危害程度对比分析，为管道建设与安全运营提供理论依据。

Through the geological hazard investigation and risk assessment of long distance pipelines, the statistical analysis indicates that moat waterlogging is one of the disaster types which develop the most and have higher risks. Its damage mode can be divided into cutting of moat bed scouring, lifting of river trenches bed sedimentation and slumping of bank slope. According to the laying method of long-distance pipelines and its relationship with moat waterlogging position, pipeline layout can be divided into crossing river valleys, passing-through river valleys, laying-along the river valleys and laying-along the bank slopes. It focuses on the long-distance gully waterlogging characteristics under different laying environments and on that basis comparative analysis of hazard degrees is made through the method of analytic hierarchy process, providing theoretical basis for construction and operation of pipeline.
