| 摘 要： | 基于兰新铁路百里风区十三间房车站附近K1476＋875～K1477＋000沿线的集沙量观测系统，对2009年试验期间该处挡沙墙防沙功能的观测进行分析．结果表明：该地区大风以9、10级为主，集沙量与微地形关系密切，集沙量沿高度方向呈指数递减；地面构筑物的存在改变了风沙流场，挡沙墙上方的积沙量随挡沙墙高度增加而减小，增加挡...

| Abstract: | Observation and analysis of the sand retaining wall's function in a strong wind sector along the Lanzhou-Xinjiang Railway show that the force 9 wind and force 10 wind are the chief strong wind there;the amount of sand moving is closely related to micro-topography,the sediments in original ground decreases exponentially along a vertical direction,the presence of surface structures changes the sand flow,the sediment above the sand retaining wall decreases with increasing wall,and the effect was significant if... |
