基于空间虚拟层合单元法的撑架连续板桥加固研究

Continuous supporting-frame plate bridge analysis based on the method of virtual laminated element

用实体退化虚拟层合单元法 ,建立多层复合板单元模型 ,对撑架连续板桥加固方案进行研究。计算结果证明 ,实体退化虚拟层合单元具有计算精度高、单元划分和模型建立简单、方便灵活等优点 ,具有很高的工程使用价值。同时 ,又证明了该加固方案的合理性和可行性。

To finish the spatial analysis of continuous supporting frame plate bridge,the method of virtual laminated element(MOVLE) was offered to build a model of laminated element.From calculation results,the advantage of MOVLE such as the best calculation accuracy,sample element division and model building is put forward. It is a good method for confirming old bridge reasonably and usefully.
