老挝南涧河面板堆石坝方案三维变形应力分析OA
3D FEM Deformation-stress Analysis of Laos Nam Chiane Concrete-faced Rockfill Dam Scheme
∶用Duncan-Chang E-B模型模拟堆石体，接触面单元模拟面板与垫层之间的接触，面板竖缝和周边缝用分离缝模拟，对老挝南涧河面板堆石坝方案进行三维有限元变形应力分析，得到了堆石体、面板的位移应力及分布规律，分析了面板竖缝和周边缝的变形。计算结果较为全面地反映了坝体的实际工作状况，为南涧河面板堆石坝的优化设计提供了依据。
The displacements and stresses of rockfill dam and face slab and their distributions are obtained, and the deformations of face slab joints and peripheral joints are analyzed through 3D FEM deformation-stress analysis of Laos Nam Chiane concrete-faced rockfill dam scheme by simulating the rockfill dam using of Duncan-Chang E-B model, simulating the contact face between face slab and cushion layer using of contact face element, and simulating face slab joints…查看全部>>
