| 摘 要： | 文中采用非线性有限元分析方法,并运用沈珠江模型作为堆石体本构模型对面板堆石坝坝体及面板做应力和变形计算。在静力计算的基础上,选择容易产生脱空的区域进行模拟脱空,主要运用隐单元方法来进行脱空问题研究,对面板的挠度和应力与面板坝的一般规律比较并做一定的分析,来论证利用有限元仿真模拟坝体脱空是一种有效的途径。

| Abstract: | The paper calculates the deformation and the stress of dam body and face for concrete faced rock fill dam with non-linear finite element method and taking Shenzhujiang model as rock fill body model. On the basis of static calculation, the void question is studied by implicit element method through selection of easy void zone. The paper expounds and proves that FEM is a effective way for the simulation of concrete faced rock fill dam body void through the comparison between the deflection and stress of concrete face and the ordinary law of faced rock fill dam. |
