PRELIMINARY SIMULATIONS OF THE FUNCTIONS OF PROT ECTION CONSTRUCTIONS AGAINST EROSION

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 protec...
