延长气田集输干线输气管道主要敷设于黄土高原地区，地形起伏较大，延河及支流、支沟纵横交错。管道在该类地区易遭受沟头前进、崩塌、岸坡冲毁等灾害的威胁，严重影响管道安全运行。文中在分析该类地区常见水害的基础上，结合近年来水害治理的经验，提出了针对黄土冲沟、黄土崾岘、高陡坎、河流侵蚀等特殊地段的水害治理方法，供其他黄土地区管道的设计、建设借鉴和参考。

The gathering and distribution pipeline in the Yanchang gas field mainly lies loess plateau region,where there are many ditches and rivers,the terrain of this region is undulate. Pipeline in the areas is vulnerable to flood threat,such as ditch e-clipsing,collapse,slope erosion and so on,which seriously impact the safe operation of pipeline. Based on analyzing common flood hazard in this area,combining with experience of water disasters governances in recent years,this paper put forward some meas-ures for flood problem in special area such as loess gully,strictured loess section,high escarpment and river. The proposed meth-ods are available for reference in piping design and construction in other loess area.
