西气东输二线甘肃段地质灾害及防护措施
|
摘要
文章以西气东输二线河西走廊段输气管道建设为例,对管道途经的多种地貌单元和复杂地质灾害地区的沙漠、山区地震和活动断裂区的分布及特点进行了介绍;分析、评价了这些地质灾害对管道的危害。针对不同地质灾害区各自的特点,提出了相应的定线原则、敷设方案、管沟开挖方法及其他注意事项。
Taking the pipeline construction of the Second East to West Gas Pipeline section along Hexi Corridor for example, this paper describes the various physiognomy as well as the distribution and features of earthquakes and active fault zones in the desert and mountainous areas where the pipeline passes through. It analyzes and evaluates the possible damages caused by geological hazards. According to the characteristics of different geological hazards, it brings forward corresponding pipeline route design principle, laying schemes, trenching methods and other matters for attention.
