摘　　要： 结合宿淮高速公路上淮安大桥实体工程,针对大跨径水泥砼桥面受力特点,建立力学分析模型对桥面铺装体系进行受力分析,找出铺装层的最不利荷载位置,研究该位置下铺装层的应力应变规律,确定铺装层设计的各个控制指标,比较移动荷载作用下铺装层的响应,为桥面铺装层设计提供力学理论依据。 In this paper, based on the construction of Huaian bridge, the mechanical analysis model is established, which is aimed at some mechanical characteristics of long span concrete bridge deck pavement. The worst positions and mechanical control design indexes of loading combination in bridge deck pavement are found, studying mechanical analysis of bridge deck pavement system and the analysis of stress and strain in it, comparing with the response by moving load, which can provide some theoretical foundations for the designing of deck pavement.
