Wind Tunnel Experiment of the Effect of Sand Prevention Measures along Gobi Highway
戈壁地区公路防沙措施防沙效应的风洞试验

Wind erosion and sand sediment are two main problems affecting highways in Gobi area of Western China.This paper investigated the effect of sand prevention measures on highways in Gobi area by simulating different highway segments and sand prevention designs in wind tunnel and surveying fields by Particle Image Velocimetry.The wind tunnel experiment results indicated that unsaturated blown sand flow played a dominant role in the sapping and abrasion of highway cross section and some effective protection mea...
