陕-京输气管线沿线地质灾害及防护对策
|
摘要
对陕－京输气管线经过的多种地貌单元和复杂地质灾害地区的沙漠、黄土、地震和活动断裂区的分布及性质进行了介绍；分析、评价这些地质灾害对管线的危害。针对不同地质灾害区的不同特点，提出不同的定线原则、敷设方案、管沟开挖方法及其他注意事项等防护对策。
This article introduces the distribution and characters of the desert,loess,seism and active faults of the many landform units and the complex geologic disaster areas passed through by Shaan Jing Gas pipeline.It analyzes and appraises the hazards caused by these geologic disasters to the pipeline,and also proposes protection measures such as the principle of route selection,the plan of preliminary design,the method of excavating pipeline trench and other points for attention etc.in accordance with the different characteristics of the different geologic disaster areas so as to ensure the transmission pipeline in safe operation.
