洮水水库工程混凝土面板堆石坝变形应力分析

Deformation and stress ananlysis of concrete-faced rockfill dam of Taoshui Reservoir project

利用邓肯E-B模型,对洮水水库面板堆石坝在施工期和蓄水期的变形应力进行有限元计算分析,获得了堆石体和面板的变形、应力分布。结果表明,所设计的面板堆石坝变形、应力是合理的。

By using the Duncan E-B constitutive model,the concrete-faced rockfill dam of Taoshui Reservoir project is calculated under the construction stage and impounding stage respectively. The deformation and stress distribution of rockfill and concrete face are obtained,which are proved to be reasonable compared with the other projects in China.The results are valuable for the design and construction of the similar dams.
