桃源水电站施工导流及临时通航方案研究

Study on Construction Diversion and Temporary Navigation Scheme of Taoyuan Hydropower Station

桃源水电站是沅水最末一个梯级电站,枢纽主要由泄洪闸、土石副坝、电站厂房、船闸等建筑物组成。可研阶段水工共提出3类9种枢纽布置方案,初选3种方案作重点比较。针对不同的枢纽布置,施工总计提出了12个分期导流及通航方案进行研究,并提出推荐方案供枢纽布置优选决策。方案比选研究思路及成果可供类似工程借鉴。

Taoyuan Hydropower Station is the last of cascade hydropower stations along the Yuan River.It is composed of sluice gate,earth-rock auxiliary dam,powerhouse,ship lock and other structures.9 kinds of layout schemes(3 categories) are put forward in the feasibility study stage,in which 3 schemes are primarily selected for comparison.A total of 12 staging diversion and navigation schemes are proposed for construction subject to the different layout,and the optimal layout schemes are recommended.The research idea and results of option selection can be used as reference for other similar projects.
