锦屏水电站截流工程的设计与施工

锦屏水电站截流工程,采用左右两岸隧洞过流,单戗单向立堵方案。龙口流速高,落差大,难度大。现场两岸地形陡峭,施工道路条件较差,施工场地狭窄。如果左岸导流洞不能按期过流,截流难度将成倍增加。借鉴三峡工程截流经验,采取合理的堤头进占方式,减少抛投料损失,保证抛投强度,确保了截流施工的顺利完成。

Design and construction of river closure project at Jinping Hydropower Plant

The scheme of the left-right bank flowing as well as single-berm and single-direction end dumping are adopted at Jinping Hydropower Plant,river closure project.The flow velocity at the closure gap is big;the drop is big,and the construction difficulties are great.Both banks topography is precipitous;the conditions of construction road are worse,the construction field is narrow.If the left bank diversion tunnel can not be used for flowing on time,the difficulties of river closure will have doubled and redoub...
