摘要: 通过对小比尺船模技术原理及特点分析,结合枢纽上下游的通航水流条件,展开对涪江冬瓜山航电工程及通航建筑物的优化布置方案的研究。结果表明:通航代表四级流量,500 t级船 队上下行最大舵角均未超过船模试验安全舵角限值(25°),上行最小航速均优于船模试验安全最低航速(0.4 m/s)。冬瓜山枢纽船闸引航道、口门区及连接段,满足四级航道的通航要求。

Abstract: Through the analysis on the principle and characteristics of small scale ship model technology,combined with the navigation flow conditions at the upper and lower reaches of the hub,the optimization of the layout of Dongguashan navigation junction and navigation structure in Fujiang River was studied.The results show that the navigation is on behalf of four stage flows.The maximum rudder angle of 500t fleet in upstream and downstream doesn’t exceed the safety rudder angle limit (25°) in ship model test,and the minimum navigation speed in upstream is better than the lowest safety speed (0.4 m/s) in ship model test.The navigation channel, entrance area and connecting section of the lock for the Dongguashan hub meet the navigation requirements of the four grade channel.

Key words: waterway engineering, small scale ship model, hub navigation, channel improvement, engineering value
