老挝南欧江五级水电站截流规划设计研究

为了实现老挝南欧江五级水电站顺利截流,结合南欧江五级水电站现场地形条件、水文、交通等因素,基于其施工导流采用分期导流的方式,分别从截流时段安排、截流标准、控制流量、截流方式、戗堤位置选择、龙口分区与控制、截流抛投材料、施工设备安排等方面进行了全面的截流规划设计,为实现老挝南欧江五级水电站顺利截流提供了技术保证。

Design of Closure Planning of Nanoujiang Stage-5 Hydropower Station

In order to achieve river closure of Nanoujiang stage-5 hydropower station in Laos successfully, considering the topography condition, hydrology condition, transportation condition on site at the station of the project, based on the stage river diversion adopted in the construction diversion of the project, a comprehensive river closure planning design was made from the aspect of closure period arrangement, closure standard, controlling flow, method of river closure, selection of closure dike location, closure gap section partition and controlling, material used in river closure and construction equipment arrangement. Thus, it provides technical assurance for river closure of Nanoujiang stage-5 hydropower station in Laos successfully.
