摘　　要：本文结合西津二线船闸整体水工模型对一、二线船闸下引航道隔流堤长度进行了试验研究,针对下引航道原方案布置和河型河势及地形等特点,进行了多方案对比试验,结果表明:由于西津水利枢纽船闸下引航道布置于弯曲河道弯顶附近,二线船闸下引航道口门区水流条件将受其影响较大,通过适当加长一、二线之间隔流堤长度,调顺下泄水流方向,改善一、二线船闸下引航道口门区的水流流态,使口门区通航水流指标基本能够满足规范要求,值得相关二线船闸借鉴。In this paper, the partition length of the first and the second-lane lock approach channel studied in project of Xijin second--lane lock hydraulic model, Under the original proposal for the layout and approach channel river type and topography, etc., for a multi--program comparative test. it shows that as Xijin lock approach channel arranged in the river bend near the top, flow condition of second-lane lock downstream entrance area will be affected greater. But through extended the interval partition length of the first and second, changed the flow direction, improved the secondlane lock the entrance area of the flow pattern, the entrance area navigation flow targets to meet the basic specifications, reference should be related to second--tier ship lock.
