摘　　要：乌江思林枢纽已建与Ⅳ级航道相适应的通航建筑物不能满足按Ⅲ级航道规划的年过坝货运量要求,拟建思林二线通航建筑物。针对拟建的通航建筑物设计方案引航道口门区及连接段通航水流条件较差的问题,进行正态物理模型研究。采用水流试验、流场实时测量与自航遥控船模相结合的方法,研究不同工况条件下通航建筑物上、下游引航道口门区及连接段通航水流条件和船模操控,通过方案优化比选,得出口门区最优方案布置和适航流量,结论是口门区最优方案为本文修改方案3布置形式,口门区最大通航流量建议采用1 793.8 m^(3)/s,解决了该通航建筑物口门区通航的关键性问题。The navigable buildings in Wujiang Silin Hub,which are suitable for class Ⅳ channel,can not meet the requirements of the annual freight volume of the crossing dam according to class III channel planning,so the Silin second-lane navigation building is proposed to be constructed. In view of the poor condition of navigable flow at the entrance of the approach channel and the connecting section of the proposed navigable buildings,we conduct normal physical model research. Using a combination of water flow test,real-time flow field measurement,and self-propelled remote control model,we study the navigable water flow conditions and model manipulation in the upstream and downstream approaches of the navigable building and the connecting section under different working conditions,and obtain the optimal layout and navigable flow rate of the entrance area through program optimization,and conclude that the optimal layout of the entrance area is the modified program 3 layout form,and the maximum navigable flow rate of the entrance area is recommended to be 1 793. 8 m^(3)/s,which solves the key problem of navigability in the entrance area of the navigable building.
