摘要
以20 m跨桥实桥试验测试结果修正有限元模型,得出符合实际工程的Abaqus有限元计算模型,对修正后的有限元模型进行弹性计算,探讨了桥面铺装厚度对装配式空心板桥整体性能的影响,得出了该桥经济合理的铺装层厚度取值。
This paper modified the finite element model with 20 meters span bridge test results and obtained Abaqus finite element calculation model according with the actual engineering. It had the elastic calculation of the updated finite element model, discussed the influence of deck pavement thickness on the whole performance of assembly hollow slab bridge, and finally obtained the economic and reasonable values of the bridge pavement layer thickness.
