小湾水电站工程关键技术研究

小湾水电站工程规模宏伟,坝高库大,泄洪功率高,单机容量大,坝址区地形地质条件复杂,地震烈度高,技术问题极其复杂,难度很高,在许多方面均属世界之最。小湾水电站工程的关键技术主要包括:枢纽总布置,高292m的拱坝设计及基础处理,高水头大流量泄洪消能,超大型地下洞室群,高水头大容量水轮发电机组,高水头大型金属结构,700m高的复杂高边坡整治等。

Study on Key Techniques of Xiaowan Hydropower Station

Xiaowan Hydropower Project(XHP) is a huge project with a lot of extremely complex and high technical problems in relation to complex topographic and geologic conditions,high earthquake intensity at the site as well as high arch dam,huge reservoir,lager discharge volume and power,lager unit capacity,etc,which are mostly on the highest world-class level in many ways.The key techniques of the XHP is described for design that including the project layout,the shape of the arch dam of 292 m in height and its foundation treatment,the discharge with high water head and large volume,the lager underground power house correlating to a series of the big tunnels,the turbine and the generator with high water head and lager volume,lager metal structures as well as the dealing with the high and complex slopes of about 700 m,and so on.
