| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
