在水的作用下,部分黄土路堤急剧变形下滑中断铁路运输,威胁行车安全,形成灾害。近年来这类灾害接连发生,仅咸铜线、太西线、铜王、乔东等专用线不到5年时间发生20余次。它大部分位于路堤路堑相连的“结合部”,来势迅猛,很易酿成重大行车事故。它的滑塌体比路堑滑坡体数量小。若能引起重视,大部分是可以事前预防的。一旦发生,后患无穷。
Under the action of water, a part of the loess embankment sharply deforms and breaks down and rail transport is interrupted, threatening the traffic safety and disaster. In recent years, such disasters have occurred one after another, only Xianghu copper, too Western Line, Copper King, Qiao Dong and other special lines occurred less than 5 years more than 20 times. Most of it is located in the “junction” of the embankment and road cutting. The situation is so rapid that it can easily lead to a major traffic accident. Its slump body is smaller than the number of landslide bodies. If attention can be paid, most of them can be prevented in advance. In the event of an affair, endless trouble.
