大朝山水电站截流规划设计

大朝山水电站于１９９７年１１月１０日成功实现大江截流。根据施工总布置，采用从右岸向左岸单戗堤立堵截流方式获得成功。采用以石渣混合料为主配合钢筋石笼等混合抛投，在大江上截流得到实现。利用上游已建成的漫湾水电站短期控泄发电，以减少下游大朝山工程截流难度，取得成功。大江截流成功，为大朝山工程２００１年第一台机组发电提供了必备条件。

Design of River Closure Planning for The Dachaoshan Hydropower Project

The river closure was executed on 10 November,1997 for the Dachaoshan Hydropower Project.According to the general layout of the construction the river closure was successfully implemented by end dumping advancing from the right bank to the left bank along a single dike.The dumping of quarry rubbish mixed with reinforcing gabions was realized in the river closure constuction.It was successful to have utilized its upstream completed Manwan HydropowerStation while it was generating electric power under control of discharge so as to minimize difficulty in undertaking the river closure for the Dachaoshan Hydropower project.The success of the river closure has provided necessary conditions for commissioning of the first generating unit of the Dachaoshan Hydropower project in 2001 .
