In the “Desert-Gobi-Desertification” region of northwest China, the transmission lines are confronted with severe wind-sand disasters, which pose a threat to the safe operation of the power grid. In power transmission lines, upright bar and bundle reed sandfences are commonly employed as sand barriers. It has been discovered that these two distinct reed sand barrier structures exhibit different sand control effects. To explore the differences in the wind-sand prevention effectiveness of the two structural sandfences, the flow field characteristics and sand accumulation patterns of the two sandfences under different wind speeds were analyzed through a combination of numerical simulation and wind tunnel testing. The results indicate that the bar sandfence generates strong viscous resistance and demonstrates a better wind prevention effect. Its sand blocking efficiency is higher than that of the bundle sandfence. However, the accumulated sand is distributed close to the sand barrier and is prone to being buried. The bundle sandfence has a smaller windproof range, but the sand accumulation is distributed in areas far from itself, and its resistance to sand burial is remarkable. Based on these findings, a differentiated layout scheme is proposed: The bundle sandfence is utilized to extend the service life in the dominant wind erosion area, while the bar sandfence is used to enhance the sand blocking effect in areas with severe sand accumulation. These results provide a basis for the optimized design of sand control engineering for desert transmission lines.
