- 摘要:
- 西气东输二线管道工程作为我国天然气四大进口战略通道中的西北通道,在全国天然气管网布局中最具战略性意义。该工程西段始于新疆维吾尔自治区霍尔果斯口岸,东至宁夏中卫,全长约2 745.9 km,管道沿途穿越盐渍戈壁、沙漠、剥蚀准平原、风蚀雅丹地貌、黄土高原、基岩山地及山前冲洪积扇等多种地貌单元,环境工程地质条件极其复杂,地质灾害种类繁多。文章简述了西气东输二线西段管道工程复杂的环境地质条件对工程的影响以及工程建设对区域工程地质条件的影响,重点讨论了管道沿线的特殊性岩土、工程地质条件和环境地质条件,并分析了其对管道建设及运营存在的危害,提出了相应的防护措施,可为管道建设工程提供借鉴。
Second West to East Gas Pipeline Project, as the northwest channel of the four great strategic natural gas import channels in China, plays the most important strategic role in the national natural gas pipeline networks. West Section of Second West to East Gas Pipeline Project has the length of 2 745.9 km from Huoerguoshi Port, Xinjiang to Zhongwei, Ningxia. The pipeline passes a variety of landforms including salinized Gobi, desert, torso peneplain, wind erosion yardang, loess plateau, rocky mountain and piedmont alluvial-pluvial fan. The environmental and engineering geology conditions are extremely complex and geologic disasters are various in kind. This paper outlines the effect of complex environmental and geologic conditions in West Section of Second West to East Gas Pipeline Project on the engineering and the effect of engineering construction on local engineering geologic conditions, discusses with emphasis on the special rock and soil, engineering geologic condition and environmental geologic condition along the pipeline, analyzes their harms to the pipeline construction and operation and puts forward corresponding countermeasures.2010,S1(S1): 6-11 收稿日期：2010-10-25分类号：TE49作者简介：沈茂丁（1978-），男，甘肃景泰人，工程师，一级注册建造师，2001年毕业于西安科技学院工程地质与水文地质专业，主要从事管道工程的工程地质勘察工作参考文献：
