混凝土面板堆石坝的垫层区,是个很重要的区域。国内混凝土面板堆石坝的垫层料有两种,一种是采用人工碎石和机制砂掺和而成,另一种是采人工碎石和天然砂掺和而成。最近,福建万安溪混凝土面板堆石坝施工中,成功地试验出了采用人工碎石和砂包土掺和而成的掺砂包土垫层料。它的使用,简化了垫层料的施工工艺,加快了工程 Concrete faced rockfill dam cushion area, is a very important area. There are two kinds of bedding materials for concrete faced rockfill dam in China, one is made by blending artificial rubble and mechanism sand, and the other is mixing by artificial rubble and natural sand. Recently, Fujian Wan Anxi concrete faced rockfill dam construction, the successful test of the use of artificial gravel and sand embankment made of sand mixed bag cushion material. Its use simplifies the construction process of cushioning materials and speeds up engineering
