Study on General Layout of Hydroelectric-Navigation Project of Guojundu in Fujiang River

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.
