| 英文摘要 | Fences are one of the most effective measures to prevent and control wind-blown sand disasters, and the blocking effect of fences is largely determined by their porosity and height (H). This study employed wind tunnel experiments to measure wind velocities on both sides of wire mesh sand fences with porosities of 75%, 63%, 56%, 36% and heights of 10, 5 and 2 cm. The effects of porosity and height on the blocking effect of the fences were evaluated on the basis of velocity variability, flow field, and the wind velocity reduction coefficient. Results show that the smaller the porosity, the stronger the blocking effect. The fence with a porosity of 36% had the strongest windproof efficiency of 0.70 and longest protection range of 9H, and thus showed the best applicability in preventing and controlling wind-blown sand disasters. The fence with a porosity of 56% showed a windproof efficiency of 0.31 and a protection range of 7H, which could be considered for adoption. However, fences with porosities of 75% and 63% were not recommended to be adopted, because their windproof efficiency and protection range were very small. Overall, the higher the fence, the stronger the blocking effect. The highest fence (10 cm) had the longest protection range of 90 cm, which was the best in application. Nevertheless, the 5 and 2 cm fences were almost consistent with 10 cm fence in windproof efficiency, which was still suitable for wind and sand fixation. |
