西部原油成品油管道工程甘肃段水土流失防治探讨

The Western Crude Oil Pipeline Engineering for Prevention and Control of Soil and Water Loss in gansu Province

中国石油西部原油管道是目前国內运输距离最长、设计压力最高、国内设计输量最大、自动化程度最高、参建队伍最多的输油管道之一.管道铺设过程中,大量采用机械施工,路堑开挖、路堤填筑、取土采石、架桥砌涵等,破坏了公路沿线原地貌及植被,扰动了表土结构,致使土体抗蚀能力降低.分析了"西油东送"工程建设(甘肃段)水土流失问题,总结了工程区自然情況.研究了管道工程建设对生态环境的影响,探讨了管道工程防护类型选择的原則,针对不同情況采取相应的防治措施.

China Petroleum West crude oil pipeline is currently the longest transport distance, the maximum design pres- sure, the largest domestic design input, the highest degree of automation, Participation team one of the largest oil pipeline. Pipe laying process, a large number of mechanical construction, cutting excavation, embankment, earth or rocks, bridges puzzle Han destroyed the original topography and vegetation along the highway, the disturbance of the topsoil structure, resulting in reduced corrosion resistance of the soil. Analysis of the soil erosion problem east of the Western oil ＂ project （ Gansu）, summed up the natural situation of the project area. Pipeline construction on the ecological environment, and to explore the principle of choice of the type of protection of the pipeline project to take appropriate preventive measures, for different circumstances.
