Sandstorm wind-resistant disaster mitigation engineering method

Abstract

The application discloses a sandstorm wind-resistant disaster-reducing system engineering method. The application relates to the cross technical field of wind-sand environment engineering and ecological management. The engineering layout area is selected according to the moving path of the sandstorm and the dominant wind direction in the sandstorm source area, the strengthening area or the main path; a high-level, middle-level and low-level wind-resistant disaster-reducing structure system is constructed according to the principle of Tai Chi using the force of the opponent to strike; a plurality of wind-resistant disaster-reducing belts are constructed in the selected area; each wind-resistant disaster-reducing belt comprises a high-level wind-resistant wind-guiding structure, a middle-level wind-consuming structure and a low-level sand-resistant structure arranged along the wind direction; the high-level wind-resistant structure is used to resist the wind in the opposite direction by artificial means, so as to consume and interfere with the overall dynamic structure of the sandstorm; the middle-level flexible barrier continuously consumes the kinetic energy of the strong wind by physical resistance and deformation, so as to reduce and alleviate the destructive power of the strong wind; and the low-level sand-resistant structure can effectively control the starting of the surface sand particles, so as to reduce the sand supply from the source.
