摘　　要：对"S"形河道中某大型航电工程上游引航道的透空形式和下游引航道不同长度的布置形式进行了模型试验,分析了上下游隔流墙布置位置及结构形式对通航水流条件的影响。研究表明:上游引航道采用上下分层透水方案能够改善回流流速,但需要控制透水流量,防止过大的透水流量导致停泊段出现不利的侧向流速;下游引航道合理的位置和角度比单纯增加长度能更有效改善水流条件。Model experiments of hierarchical permeable structure of upstream approach channel and different length of downstream approach channel of a large navigation and hydropower project in＂S＂shaped river were conducted. The influence of the layout position and structure of upstream and downstream partition wall on navigable flow conditions was analyzed. The results show the reflux flow rate can be improved by the application of the hierarchical permeable structure of upstream approach channel,but the permeable flow discharge need to be controlled,in case that excessive permeable flow causes unfavorable lateral flow rate at parked segments. The reasonable position and angle are more effective than simply increasing the length to improve navigable flow condition of downstream approach channel.
