| 摘 要： | 针对拱梁分载法无法较真实模拟地基的不足,提出了一种简单的拱梁分载法与有限元地基耦合分析法,并推导了拱梁单元节点位移和转角与坝基实体单元节点的协调关系,较好地解决了在建基面坝体和地基节点的自由度不协调问题。实例结果表明,建模简便灵活、方法正确有效。

| Abstract: | Aimed the shortcomings that the arch-cantilever method can not simulate the foundation truly,so the paper has proposed a simple arch-cantilever method coupled with finite element analysis of foundation,and derived that the displacement and angle of arch beam element node have the relation and coordination with node solid element of dam foundation.The method can relatively simply solve the node freedom non-co-ordination problem in the dam foundation surface.And the model is also to built conveniently and fle... |
