西北黄土湿陷性地区管道地质灾害类型分析
|
摘要
随着长距离油气管道的不断投入建设和运营,管道的地质灾害问题正在引起大家的关注。通过对管道穿越西北湿陷性黄土地区遇到灾害特征进行研究和总结,并结合一部分具体的实例进行分析得出以下结论:(1)西北地区管道地质灾害类型主要包括滑坡、崩塌、泥石流、黄土湿陷和水毁等5类灾害,其中水毁最为严重;(2)水毁主要的作用方式包括河沟段下切作用和河岸侵蚀作用;(3)由于河沟段的下切作用和河岸侵蚀作用,水毁形式主要表现为漂管、悬挂、推移等3类形式。
With the continuous investment, construction and operation of long-distance oil and gas pipelines, the geological hazards of pipelines are attracting attention. The disaster characteristics of the pipeline passing through the northwest collapsible loess area are studied and summarized, and combined with a specific example of analysis draws the following conclusions:(1) the type of geological disasters in Northwest Region mainly include landslide, pipeline collapse, debris flow, loess and water damage and other 5 kinds of disasters, which damaged the most serious;(2) the main damage mode of action includes cutting action and river bank erosion period;(3) due to cutting effect and invasion of riparian rivers, flood forms such as drift tube, suspension, over 3 kinds of forms.
