摘要
以常用的13 m跨径空心板桥为代表,为了得到更加符合实际情况的模型,在建模时考虑铺装层参与桥面板共同受力的作用.利用有限元软件ABAQUS6.8进行空间实体建模和计算,对不同铺装层参数(厚度、模量、泊松比)影响下的铰缝结构的应力和变形进行分析,最终得到铺装层参数对铰缝结构受力性能的影响规律.
For the study,the commonly used 13 m hollow slab bridge is taken as an example.In order to build a model closely conforming to the actual case,the slab and bridge deck pavement are considered as a whole to bear the loads.Finite element software ABAQUS6.8 is used to establish an entity model and calculations are carried out so that the stress and deformation of hinge joints under different bridge deck pavement parameters（thickness,modeulus,and Poisson ratio） can be analyzed.In the end,the regular influence of pavement parameters on stress and deformation of hinge joints is deduced.
