面板堆石坝流变特性研究

Research on Rheological Characteristic of Concrete Faced Rockfill Dam

简要介绍了某水电站混凝土面板堆石坝工程概况和流变计算模型。采用三维有限单元法对该混凝土面板坝筑坝及蓄水过程进行模拟计算,对比考虑堆石料流变和不考虑流变的两种计算结果,分析说明筑坝材料的流变特性对面板坝坝体以及混凝土面板变形应力的影响。

The overview of a concrete faced rockfill dam（CFRD） project and rheological models of rockfill were presented brief- ly. The 3--D finite element method was used to simulate and calculate damming and the impounding process of the CFRD. By contrasting the result from taking into account the rheological effect with that from without taking account of rheologieal effect of roekfills, the influence of rheological behavior of rockfill on deformation and stress of dam and face slab were analyzed and studied.
