| 摘 要： | 三峡蓄水后荆江河段河道普遍冲刷、航道整治护滩工程的促淤效果有待提高。采用多种网片等间距构建形式，提出了一种新型可控式网箱透水促淤结构。通过水槽试验，研究不同流速、不同水深以及不同布置形式下的可控式网箱结构的减速、促淤效果。该结构有效改善了工程区域水流条件，在较大的空间内降低流速，实现促淤固滩的目的。

| Abstract: | After the impoundment of the Three Gorges Reservoir,scouring often exists in Jingjiang River channel,in which the promoting siltation effect needs to be improved. A new type of controllable net cage structure which is ormed by meshes with equal interval is proposed.By flume experiment,the decelerating and promoting siltation effect has been analysed in different velocity,water depth and positions.The structure can improve water flow conditions in engineering areas,lower the low rate in the large spce,and achieve the purpse of siltation promoting. |
