摘要:: 纤维材料沙袋沙障是一种新兴的固沙材料，具有施工运输方便，可重复利用等优点。通过在古兰泰铺设纤维沙袋沙障，分析了1 m×1 m不同孔隙度（15%，25%，35%）三种规格对风速廓线、输沙量、粗糙度等的影响。得出了低立式纤维材料沙袋沙障具有明显的防风固沙效应，三种规格沙障对风沙流结构的影响不同，35%规格对风的削弱作用最强；三种规格都具有明显的控制风蚀基准面作用，其中15%规格的对风蚀基准面的控制最稳定；由于沙袋的特殊性，其障内地表曲面不同于一般格状沙障的稳定凹曲面，与风向有一定的相关性。

Abstract:: The fiber material is a new sand-fixation material. It has characteristic properties of convenient transport and reuse. This paper mainly studied the effect of the low-fiber sandbag sand-barrier on wind-breaking and sand-fixation, and analyzed the effect of wind speed profile, sediment and surface roughness about three different porosities (15%, 25%, 35%) of 1 m×1 m. As a result, the effect of the low-fiber sandbag sand-barrier has the obvious effect on wind-breaking and sand-fixation. Different specifications have different impacts. The specification of 35% has obvious ability to low wind speed. All the three means have control erosion base level, especially the specification of 15% is very good for controlling the base level of erosion. In the sand-barrier, the ground surfers are different from those of others sand barriers, and have correlation with wind directions.
