摘要
采用二维弹塑性有限单元法对成屏混凝土面板堆石坝施工填筑期和水库蓄水运行期的应力变形进行了模拟分析 ,研究了不同阶段坝体的应力变形状态 ,特别是面板的应力变形以及周边缝变形。计算中考虑了坝体堆石料的流变特性 ,计算结果较为全面地反映了大坝的实际工作状况。
The construction and run process of Chengping concrete-faced rockfill dam was analyzed by using a planar elastic-plastic finite element method.Rheologic characteristic of the rolled rock is taking into account of the calculation.As compared with the observation data,it shows the resulit in fairly accordance.
