摘　　要：筑坝材料特性的研究是面板堆石坝设计研究的关键工作之一。为了减少对工程区周边环境的影响,加快施工进度,充分利用当地砂岩料和建筑物开挖料,本文以铜灌口水库混凝土面板堆石坝为例,对筑坝材料进行了大型静动力三轴和大型流变试验等室内外试验研究,在试验结果基础上进行了大坝静力应力变形特性的三维有限元分析、三维流变分析和坝坡稳定分析,合理优化了坝体填筑材料,确定了大坝结构设计方案。The study on characteristics of dam construction materials is one of the key tasks in the design of concrete faced rockfill dam. In order to reduce the influence on surroundings of the project area, speed up schedule of construction and make the best of the local sandstone and building excavated materials, this paper studies the interior and outdoor tests such as the large-scale static dynamic tri axial and theological tests for the dam construction materials taking an example of concrete face roekfill dam of Tongguankou Reservoir. On the basis of the test results, 3-dimensional finite element, 3-dimensional rheological and dam slope stability analyses of the dam static stress deformation characteristics are carried out. The dam body filling materials are optimized rationally, and the dam design scheme is determined.
