摘　　要：针对潜没式导流护滩带,采用理论分析与概化水槽试验相结合,开展潜没式导流护滩带的导流效果研究。结果表明,导流护滩带对水流具有较好的调整作用,其调整作用表现为受导流护滩带阻挡的水流向主流侧偏移以及主流侧过流量增大,调整作用的大小受护滩带阻水程度和淹没程度的影响。主流偏移相对距离和导流率能较好地评价护滩带的导流效果。Regarding the beach protection belts in submerged type, we apply the method of combining theoretical analysis with the generalized flume test to study the diversion effect of beach protection belts in submerged type. The results show that the diversion beach protection belt has a good regulative effect on the water flow. The efficiency of the beach protection belts is expressed by the offset distance and the increase discharge of the main stream. The efficiency of the beach protection belts is affected by the water-blocking ratio and the submergence of the beach protection belts. The offset distance of the main stream and the rate of the offset discharge can well evaluate the efficiency of the beach protection belts.
