The theory and research methods of wind-sand two-phase flow have become mature, mainly focusing on the physical movement of wind-sand and wind-sand consolidation engineering. However, the study of wind-sand movement phenomenon and its effect on building structures is relatively rare. It is of great practical and engineering significance to continue the research on wind-sand resistance of engineering structures in wind-sand areas. In view of this, the wind field characteristics under the actual desert landform are simulated through wind tunnel test. The variation of sand consistency, wind velocity profile and turbulence intensity with height under the similar sandstorm environment is mainly studied through the falling sand on the top of the wind tunnel. By controlling the same wind speed and changing the sand transport rate, sand fall is carried out to form a variety of different types of wind-sand two-phase flow coupled flow field and compare with the non-sand-driving wind. The experimental results show that the distribution of sand consistency is related to the number of sand holes, the control of wind speed and height; the movement of sand particles in wind-sand flow field weakens the wind velocity profile, but enhances the turbulence intensity; the influence of the presence of sand particles in wind field on the wind speed at different heights is directly related to the vertical distribution characteristics of sand consistency, and the larger the sand consistency is, the weaker the wind speed is, and the stronger the turbulence intensity is.
