混凝土面板堆石坝筑坝材料工程特性研究

水布垭工程正在进行可行性研究。混凝土面板堆石坝方案，坝高２３３ｍ，大大超过国内外已建和在建的同类坝型中的是高面板堆石坝设计工作中的关键工作之一。为此，针对水布垭工程的具体情况，对筑坝材料的级配，压实密度孔隙率，压缩模一，排水性能，强度和应力应变等特性进行了大量的室内外试验研究。

Study on properties of rockfill materials for alternative concrete faced rockfill dam

Shuibuya Hydroelectric project is under feasibility study. For the scheme of concrete faced rockfill dam, the dam heigt will reach 233 m,largely surpassing the highest one of the same type existing and under construction at home and abroad. The study of deformation characteristics for rockfill materials is one of the key tasks in the design of high concrete faced rockfill dam. For this reason, large amount of tests and studies on rockfill materials in laboratory and field have been done, such as gradation, compacted density, porosity, compressive modulus, drainage capacity, strength and stress strain relation. The results show that it is feasible to make use of local materials to construct high concrete faced rockfill dam for Shuibuya project.
