在水工建筑物中,灌浆帷幕作为主要的垂直防渗设施得到广泛的应用。乌江渡水电站的胜利建成,其高压水泥灌浆帷幕的显著效果为我国岩溶地区水电建设和防渗帷幕的设计施工提供了十分宝贵的经验。随着水利资源的大力开发,在强岩溶地区水坝建设愈来愈多,岩溶水文工程地质条件也愈来愈复杂。特别是近些年来,在丘陵盆地及河流中下游强岩溶宽敝河谷上建坝的工程屡见不鲜。如澧水下游正在施工的三江口水电站即是一例。就是一个位于新华
In hydraulic structures, grouting curtains are widely used as the main vertical seepage control facilities. The victory of Wujiangdu Hydropower Station was completed. The remarkable effect of the high-pressure cement grouting curtain provided a very valuable experience for the construction of hydropower and anti-seepage curtain in karst areas in China. With the vigorous development of water conservancy resources, more and more dams are built in strong karst areas, and the geologic conditions of karst hydrological engineering are also getting more complicated. In recent years, in particular, the construction of dams on the heavily karst valleys in the hilly basins and in the middle and lower reaches of rivers has not been uncommon. For example, the Sanjiangkou Hydropower Station under construction in the lower reaches of Huangshui is an example. Is a Xinhua
