Abstract: According to the study on hydraulic model tests of Guojundu hydroelectric-navigation schemes,the changes of the sediment despite and navigable flow conditions in the entrance area of upper and lower approaches are discussed.The plane layout of division channel of ship lock,the sailing circumstance and main factor of designing fleets at the upper and lower entrance of approaching channel and the linkage section in different navigable discharge situations are studied.The design of routes in and out ship lock is optimized.The modification of the plane layout of ship lock approach channel is proposed according to the observation on navigation flow condition.And then the recommended plan with better navigational condition,less load of engineering and more stability of bed evolution will be selected out.

Key words: Guojundu junction, plane layout, scheme, navigation, hydraulic model test

摘要： 根据过军渡电航枢纽工程水工模型试验,论述了上下游引航道口门区泥沙淤积与通航水流条件的变化,研究了船闸引航道的平面布置及不同通航流量情况下设计船队在船闸上下游引航道口门区及连接段的航行情况和航行要素,优化进出闸航线,并配合通航水流条件的观测对船闸引航道平面布置提出修改意见,从而选出通航条件好、工程量小、河道演变较稳定的推荐方案。
