摘　　要：总结了国内外透空式导流结构改善船闸引航道口门区通航条件应用情况,针对已建五强溪枢纽船闸下引航道口门区受山区复杂条件限制,中、洪水期通航条件较差的碍航问题,采用1:100整体正态定床物理模型试验,对比研究了多种透空式导流结构的整治措施对水流条件的改善效果,提出了适用于山区复杂条件下改善船闸口门区通航水流条件的新型结构——导流屏,可为同类项目提供借鉴参考。The application of permeable diversion structure to improve navigation conditions in the entrancearea of the ship lock was summarized. Aiming at the problem of navigation obstruction in the entrance area of thelower approach channel of the Wuqiangxi junction shiplock, which was restricted by the complex conditions inmountainous areas, and the poor navigation conditions in the middle and flood periods, a1 ： 100 integral normal fixed bed physical model test was can＇ied out to study the improvement effect of various kinds of permeable diversionstructures on the flow conditions. A new type of diversion vanes suitable for improving the navigation flow conditionsin the entrance area of ship locks under complex conditions in mountainous areas was proposed, which can providereference for similar projects.
