【摘要】 建议了一个堆石料流变模型， 给出有限元求解方法． 对水布垭面板堆石坝进行了考虑堆石流变性的应力应变分析． 结果表明， 堆石流变性对结构的性态会有比较大的影响， 特别是对面板的应力状态影响很大． 对于分期浇筑面板、分期蓄水的大型面板堆石坝， 考虑施工期堆石的流变性是必要的．更多还原

【Abstract】 In this paper,a rheological model for rock\|fill material is proposed and a method for solving is suggested.Based on the 3\|D FEM,the computation of a concrete rock\|fill dam is carried out.The results show that the rheology of rock\|fill material has effects on the dam,especially on the concrete faced slab.It is necessary to consider the rheology of rock\|fill material in large dam design in various stages including construction and reservoir impounding period.更多还原
