结果表明：车体迎风面及背风面表面压力分布规律基本一致，验证了数值模拟计算模型的准确性；
The results show that the pressure distribution on external surface at both windward and leeward is basically the same.
此外，迎风角的微小改变，对建筑物的受力情况影响很大，即使是对称结构，当风向与建筑物表面不垂直时，扭转效应也非常明显。
Distinguished torsion response will occur when the direction of wind is out of perpendicular to the building surface, even for the symmetric structure.
粒度分析也表明，沙丘迎风坡表面粒度特征主要取决于表面蚀积状况，同断面形态表现出密切的相关性。
Grain size analysis also indicates that grain size characteristics are mainly influenced by intensity of erosion or deposition and morphology of windward slope.
