因为风洞实验具有较强的可操作性，并且能够从复杂的诸多因素中分离出单独的某一影响因素进行分析。利用风洞实验模拟大自然环境，对不同防风网的挡风抑尘效果进行实验测试；对不同颗粒粒径的沙堆进行粒径分析实验，并结合模拟的流场分布进行了对比分析。防风网的设置能够明显的降低沙堆扬尘量，沙堆迎风面的扬尘最严重，且导流型防风网的堆前存在降尘区域。

The wind tunnel experiment has strong maneuverability, and can isolate the separate influencing factor from complex factors. In this paper, the wind tunnel experiment was used to simulate nature environment, the wind dust-controlling effect of different windproof net was tested; Grain size analysis experiment was carried out by using sand with different particle size. Combined with simulated flow field distribution, experiment results were compared and analyzed. The results show that the windproof net can significantly reduce the amount of sand dust;Fugitive dust is the most serious on the windward side, there is dust fall area in front of the sand pile with deflector-porous fence.
