兰成渝输油管道选线方案的比选

Determination on Route Scenario for Lanzhou-Chengdu-Chongqing Products Oil Pipeline,

通过对兰成渝管道总体线路走向和对各段设计方案进行比选,确定了最优线路设计方案。对途经的极复杂管道段的选线进行了举例分析,指出山区管道线路与隧道相结合设计方式是兰成渝管道选线的重要特点,管道选线设计中隧道的应用可以更新管道线路设计的观念,提高管道线路的安全性,减小管道施工难度。

The comparison and selection are made on the overall trend and design scenarios of different pipelinesections for Lanzhou-Chengdu-Chongqing Products Oil Pipeline. The optimal routing design scenario is determined based on the comparison and selection results. A case analysis on the route selection for the most complicated pipeline section is carried out. It is pointed out that the pipeline route selection of Lanzhou-Chengdu-Chongqing Products Oil Pipeline in design should be integrated the mountainous pipeline route into tunnel,which can overcome the difficulties of pipeline construction and ensure the safety of the pipeline route.
