| 摘 要： | 应用梁格法建立空间有限元模型,对比分析了当新桥采用普通空心板和宽幅空心板时,旧桥的内力状态。并且分析了新桥截面的刚度以及跨径对旧桥减载效果的影响,对空心板梁桥拓宽结构的设计有一定的参考价值。

Selection Analysis on New Bridge Section of Widening Structure of Hollow Slab Beam Bridge |

| Abstract: | Apply beam grillage method to build space finite element model,and compare and analyze the status of internal force of the old bridge when new bridge uses common hollow slab and wide hollow slab.The rigidity of new bridge section and the influence of span on deloading effect of the old bridge are analyzed,providing a certain referential value for the design of widening structure of hollow slab beam bridge. |
