纵坡段桥面铺装层的受力分析

针对桥梁中广泛存在的上下坡段、坡道坡度大等问题，进行了纵坡段桥面铺装层受力分析。首先，分析纵坡段桥面铺装病害的原因；其次，引入动荷载，分别计算桥面在静载和动载作用下的力学响应；最后，分析坡度、刹车和超载等因素对桥面铺装的抗剪稳定性的影响，从而为山岭、丘陵地区桥梁铺装提供可靠的技术保证。

Force Analysis of Longitudinal Slope Section of Bridge Deck Pavement

For the widespread presence of big grade on the slopes of bridges,the force analysis of longitudinal slope of brdge deck pavement was carried out.First,the causes of deck pavment diseases on longitudinal slope were analyzed;secondly,dynamic load was introduced to calculate the mechanical response of bridge deck under static load and dynamic load;finally,the impact of slope,braking and overload on the shear stability was analyzed, so as to provide a technical assurance for the deck pavement in mountains and ...
