摘　　要：对某露天料场在常年主导风速的情况下,数值模拟分析了其在有无防风抑尘网及不同网高条件下的工况。结果表明,防风抑尘网对风流导致的粉尘扩散有良好的控制作用,在网高约为料堆高度1.1~1.3倍时,综合效果最佳。The different effectiveness of porous fences in open-air depots were analyzed based on numerical simulation different conditions under the same wind velocity,whice contain whether have porous fences and the height of porous fences.the results show that porous fences have a good control action to the dust proliferation caused by wind,it will have best comprehensive effect when the height of porous fences is 1.3 times of pile.
