Abstract
Based on the large number of field surveys and long-term monitoring data of Hongceng, Hongliu and MengliuDong monitoring points, the wind-sand flow movement characteristics along the railway in Gobi area was analyzed. The shielding effect of the wind-break wall was evaluated by the methods of numerical simulation and field test. Conclusions drawn as followings: the wind-sand flow movement in Gobi area is characterized by stable of direction, seasonal, high-velocity,long-term,and shorting of starting-up time and moresand content. Numerical simulation shows that the wind flow form a large vortex region on the leeward side of wall, the flow field elements occurs significant changes. Both field test data and numerical simulations indicated that 3.0m height of wind-break wall meet the requirement of shielding wind-sand flow.
