摘　　要：结合桥面混凝土铺装的试验研究和有限元分析结果 ,对桥面混凝土铺装破坏的力学机理进行了阐述 ,初步提出了其设计标准。同时对复合铺装结构的计算模型作了探讨 ,并对复合铺装结构由于沥青混凝土加铺层与下部混凝土结构存在的弹性模量的差异 ,引起的下部桥梁结构应力重分布进行了分析。Aimed at the experimental study about concrete bridge deck and the results analyzed by FEM methods,this paper expatiates the destroying mechanism of concrete bridge deck pavement and brings forward its designing criterion.This article also discusses the stress redistributing influence in different layers of bridge structure,which was caused by the difference of elastic modulus between asphalt concrete overlay and concrete bridge structure,and the design model of concrete bridge composite pavement structure.
