摘　　要：针对三峡水库蓄水后,来沙量大幅减少的实际情况,在长江中游荆江窑监河段新河口边滩护滩工程缓流区,开展了仿柔性植被水草垫促淤结构现场试验,取得了较好的工程效果。对水草垫促淤结构的设计思路、构件设计、促淤机理和施工工艺进行阐述,并对工程效果进行分析。该结构丰富了航道整治工程促淤结构形式。The sediment is dramatically reduced after the impoundment of the Three Gorges Reservoir.Experiments on the sediment deposition effect by the soft waterweeds structures are carried out in the low flow velocity region of the beach protection area of the Jingjiang Yaojian reach in the middle of the Yangtze River.This paper introduces the design idea, components design, sediment deposition mechanism and construction procedure of the waterweeds pats.The effect of the project is also analyzed.This new structure enriches the sand deposition structures.
