- 摘要:
- 西气东输管道和西气东输二线管道并行段的路由基本形成了我国西气东输管道的重要管廊带,而中卫站也将成为西气东输的重要枢纽站。结合西气东输二线西段宁陕段线路工程设计和施工的工程实践,总结了工程建设中涉及的主要问题,其难点主要体现在黄河西岸段约23 km范围内多次穿越活动断层、黄河东岸段约6 km地形复杂路由困难、中卫站至中宁古城子段存在大量液化土段。线路工程中其他应关注的问题主要是风蚀沙埋危害、管道穿越引黄灌渠和古长城等。相应的路由建议可为规划设计中的西三线、西四线等新建管道在该地区的设计提供参考。
The routs of the parallel pipeline sections of West to East Gas Pipeline and Second West to East Gas Pipeline construct basically the important pipeline corridor belt, and Zhongwei station is an important junction center. Based on the route design and construction practice of Ning-Shan section of Second West to East Gas Pipeline, the main concerned problems in the project are put forward in this paper, including crossing many times the active fault zones along 23 km long west bank of Yellow River, difficult route selection along 6 km long complex east bank of Yellow River and lots of liquefied soil sections from Zhongwei station to Guchengzi of Zhongning. The other concerned problems include wind erosion and sand coverage dangers,pipeline crossing irrigation cannels linking to Yellow River and ancient Great Wall. The presented route selection suggestions will provide a reference for some new pipelines in those regions such as planned Third West Pipeline and Fourth West Pipeline.2010,S1(S1): 34-36 收稿日期：2010-10-25分类号：TE973.1作者简介：谌贵宇，工程师，1987年毕业于西南石油学院油气储运专业，主要从事油气管道施工管理工作
