摘　　要：近年来国际上修建了一些 15 0～ 190m高的混凝土面板堆石坝 ,目前还有 7座坝高为 15 0～ 2 40m高的面板坝准备开始修建。但是已修建的这些高坝较普遍地发生了面板结构性裂缝 ,有些坝结构性裂缝宽达 5 0mm ,个别坝还发生垫层料的流失。通过对天生桥一级水电站面板堆石坝原型观测资料的分析 。In recent years, some concrete face rockfill dams each with a height of 150 190 m have been built in the world. At present, there are still 7 concrete face rockfill dams each with a height of 150 240 m that will be started to build. But the structural cracks generally take place in the face slabs of these high constructed dams. Some cracks are up to 50 mm wide. In a few dams, the cushion material loss occurred. On the basis of the analysis on the prototype observation results from the concrete face rockfill dam of Tianshengqiao First cascade Hydropower Station, the author put forwards some suggestions on improving the design and construction of concrete face rockfill dam.
