黄河上游某水电站施工导流设计

Construction diversion design of a hydropower station in the upstream of the Yellow river

某水电站地处西北高原寒冷地区,且位于高山峡谷之中,综合考虑坝址区地质地形条件、水文气象特征、水工枢纽建筑物特点、导流建筑物布置、主体工程施工等因素,采用隧洞导流、围堰一次截断河床的导流方式,可节约工程工期,提高发电经济效益和社会效益,同时可为大中型高山峡谷寒冷地区水利枢纽导流设计提供参考。

The hydropower station is located in the cold and gorge area of the Northwest Plateau.Taking into account the topographical and geological conditions of the dam site area,the hydrological characteristics of the river,the layout characteristics of the hydraulic structure,the layout conditions of the diversion buildings,the construction of the main works,the diversion mode of tunnel diversion and primary closure cofferdam can save the project period,improve the economic benefits of power generation and social results.At the same time,it can provide a reference for the diversion design of large and medium hydropower stations in cold and gorge area.
