摘要
随着我国水电资源的进一步开发,混凝土面板堆石坝作为一种适应性强的经济坝型将成为首选。面板堆石坝的关键技术问题是要解决面板混凝土的裂缝问题,分析了面板结构裂缝和非结构(温度)裂缝的成因,并列举了一些工程上常用的防止面板裂缝的措施,引用了天生桥一级水电站面板堆石坝的面板施工措施,探讨了对面板的保护。
With further development of hydropower resources in China,concrete faced rockfill dam will be first selected due to its adaptability and economy.The technical challenges of this type of dam is slab concrete cracking.Causes of slab structural cracking and non structural cracking(thermal cracking)are analyzed here.Some conventional measures taken for preventing slab from cracking are provided,especially slab construction methods applied in Tianshengqiao I hydropower station CFRD,and slab protection is discussed.
