摘要
针对钢桥面环氧沥青混凝土铺装结构,建立正交异性钢桥面铺装三维力学模型,研究低温-重载耦合作用下钢桥面铺装的力学特性,并与不考虑温度作用的结果进行对比分析。结果表明,低温-重载耦合作用下钢桥面铺装拉应力显著增大,最大拉应力可达荷载单独作用的四倍。
Aimed at the steel bridge deck pavement of epoxy asphalt concrete, the three-dimensional mechanical model of orthotropic steel deck pavement is established to study the mechanics characteristics of steel bridge deck pavement under the low-temperature and overload coupling conditions, and to compare and analyze the results without considering the temperature condition. The results show that the tensile stress of steel bridge deck pavement under the low-temperature and overload coupling conditions increases significantly and the maximum tension stress can be up to four times of the overload alone.
