铺装层对空心板桥横向分布系数的影响研究

Research on the Effect of Pavement Layer on Horizontal Distribution Coefficient of Plate Bridge

近年来,对混凝土桥梁铺装层的研究,主要侧重于铺装层本身的受力分析,未考虑叠合效应对主体结构的影响,对铺装层的叠合效应少有研究。事实上,随着技术的不断发展,铺装层耐久性得到提高,铺装层与板梁桥之间粘结良好,因而应考虑铺装层对板梁桥受力性能的影响。本文通过力学理论计算,并结合有限元分析,对这一问题进行深入探讨,定量描述了铺装层对桥梁横向分布系数的影响程度。

In recent years,the research on bridge pavement is primarily focused on the pavement stress analysis,the composite effect of the main structure is not considered,and the composite effect of pavement research is rare.In fact,with the development of technology,the durability of bridge pavement is improved,and the pavement layer is bonded well with the plate girder.So we should consider the effects of bridge pavement on the mechanical properties of plate girder.According to the mechanical theoretical calculation and the finite element analysis, we discussed this issue in depth, and described quantitatively the effects of the pavement layer on plate bridge performance.
