摘要: 沙埋是沙漠铁路的重要病害形式之一。它是沙漠铁路在运营中造成缓行、停车甚至脱轨的重要原因。我们采用过多种防沙措施, 积累了许多经验, 如: 覆盖沙面、设置沙障、挖截沙沟、固沙造林等。在这些措施中, 以固沙造林效果最好, 具有长期效益, 是治沙的根本途径, 而其它措施只不过是临时性办法, 且要配合使用。

Abstract: The Study introduces detailly the testment for Stabilizing sand by sprinkling emulsive asphalt and by planting psammophytes at the localities of K369 and K375 of Baotou-lanzhou Railway line from 1968-1970. In the semi-desert area with more than 140 mm of rainfall, it is possible to recover vegetation by combining the sprinkling of emulsive. asphalt with the plantation of psammophytes, In the study, the method is regarded as a way with bright future to stabilize sand, that is to say, the emulsive asphalt materials costs cheaply, source of supply comes sufficiently and the machinization standard for constructing operates highly.
