| 摘 要： | 介绍堆石体的几种本构模型 ,用二维有限元方法分析了混凝土面板堆石坝的应力变形特性。用邓肯E—B模型和双屈服面模型计算了同一个 10 0m高的均质坝 ,其计算结果是堆石体的位移分布与应力分布都相同 ,但邓肯模型的位移值、应力值都比双屈服面模型的大。

| Abstract: | The article introduces several structural models, as well as analyzes the stress deformation feature of concrete face rockfill dam using two dimension finite element method. The same homogeneous dam with 100 m height was calculated using Duncan E B and double yield surface models, the results is that the distributions of displacement and stress of rockfill body are same, but the values of displacement and stress of Duncan model are lager than double yield surface one. |
