摘要
利用流体力学的实验手段,对我国西北砾漠大风地区路基工程进行了充分的物理模拟研究,从而验证了已经采用的路堤、路堑、挡沙墙和截沙沟等工程方案的正确性,为防风蚀工程的措施提供了科学依据,同时也证明了实验结果的有效性。
The practical problems of wind erosion damages of railway embarkment and the effectiveness of the engineering designs of protection constructions were explored by means of laboratory simulations.The simulation results, which are described in the present paper, show the rationality of various engineering designs for wind damage prelection used in Northwest China area. The experimental results are of help, as well, in understanding the processes of wind erosion, wind dri-ft and the functions of various protection constructions.
