界面缺陷对桥面铺装层受力的影响

Influence of Interface Defect on Load Bearing of Flooring Layer

以装配式钢筋混凝土简支空心板桥为分析对象,通过对桥面铺装层与桥面板之间有无界面缺陷情况的三维有限元计算,分析了桥面铺装层的受力特性和界面连接状况对层间剪应力分布的影响,为铺装层设计和施工提供参考。

As object with assembled reinforced concrete simply - supported bridge of voided slab,on the basis of calculation of three - dimentional finite element（ calculating if there is interface defect between flooring layer and floor slab） ,the paper analyzes the load bearing behavior of flooring layer and the influence of interface connecting state on distribution of shear stress between layers, which can provide reference for design and construction of flooring layer.
