摘要
针对西气东输工程(甘肃段)管道沿线地质灾害现状,本文重点论述了影响管线施工及运营安全的崩塌(不稳定斜坡)、泥石流、洪水冲蚀、风蚀沙埋、特殊岩土灾害的分布和发育特征,并结合线状工程的特点及各种地质灾害的发育特征和危害程度,提出了防治措施,为管道沿线防灾、减灾及灾害治理提供一定的指导依据。
Based on the current situation of geological disasters on the West-East Pipeline Project （Gansu）, this paper focuses on the distribution and development characteristics of those geologic hazards, such as collapse （slope instability）, mudflow, flood erosion, wind erosion and sand bury, special geotechnical disasters, which have the impacts on pipeline construction and operation safety. Combining with the characteristic of linear streched project and a variety of geological disaster characteristics and damage degree, the prevention measures are given, as a guiding to disaster prevention, reduction and control along the pipeline.
