西流水面板堆石坝三维流变分析

采用考虑堆石料流变性的分析模型，对西流水混凝土面板堆石坝进行了三维非线性有限元计算，得到了考虑堆石流变性后的坝体、面板及接缝的位移和应力，同时对比分析了堆石料流变性对混凝土面板堆石坝结构性态的影响．结果表明，虽然堆石流变性对大坝工作性态有一定影响，但对西流水面板坝而言，在考虑堆石流变性影响后，其设计方案在技术上仍是可行的．

3-D rheological analysis of Xiliushui Concrete Face Rockfill Dam

The 3-D nonlinear finite element method with consideration of the rheology of rockfill materials is used for simulation of the construction and water storage processes of the Xiliushui Concrete Face Rockfill Dam. The stress and deformation of the dam body, the face slab, and all kinds of joints are obtained. A comparative analysis shows that the rheology of rockfill materials has some influences on the structural performance of the dam, but the design of the Xiliushui dam is still feasible in technology when the rheology of rockfill materials is taken into account.
