摘要
戈壁风沙流是西北地区一种较为常见的风沙灾害,严重威胁到铁路的建设与运营,以酒额铁路为例,采用现场调查和室内分析的方法,对该地区戈壁风沙流结构、特征、形成原因及危害形式进行分析,结合酒额铁路所经区域的自然地理、气候特征等条件,提出戈壁风沙流地区选线的基本原则,阐述以预防为主防治结合的治沙思路和植被防沙为主、工程防沙为辅的防治措施。
Gobi wind-sand flow is one of the typical sand disasters in northwest of China that severelythreatens the railway construction and operation. With reference to Jiuquan to Ejina Banner railway, theconfigurations, characters, causes and harms of wind-sand flow in Gobi region are analyzed by means offield investigation and laboratory test. This paper puts forward basic principles for route selection in suchregion in view of physical geography and climate factors. Additionally, prevention is prioritized incombination with vegetation protection and supplemented engineering protection.
