摘　　要：水毁灾害是长输油气管道中普遍存在且会间接危害管道安全的特殊灾害,其不同于崩塌、滑坡、泥石流等常规地质灾害会造成瞬间、毁灭性的破坏,通常会导致管道上覆土体被冲蚀、管道护坡工程被破坏,造成露管、悬管、漂管等危害。结合多年来在管道保护上的工作经验,总结了水毁灾害的发育影响因素,深入分析了水毁灾害对管道可能造成的危害,并提出了合理的防治措施建议。For most long-distance oil and gas pipelines, flood hazards are not only common but also special ones to indirectly damage pipeline safety. Different from other geological hazards such as collapse, landside, and debris flow resulting in instantaneous and destructive effect, the flood hazards often lead to many problems of eroded overlying soils, destructed slope protection, and damages including exposed, hanging, and floating pipelines. In this study,some factors affecting the development of flood hazards are summed up, the damages possibly brought to pipelines are analyzed, and several suggestions on protective measures are made.
