摘要:
采用力学近似方法,对钢桥面沥青混合料铺装层在循环荷载作用下的力学行为和疲劳损伤特性进行了理论分析.采用粘弹性损伤模型的能量转换方法对钢桥面沥青混合料铺装层应力场、应变场及损伤场分布状况进行研究.依据钢桥面沥青混合料铺装体系复合结构的应力场、应变场和损伤场在疲劳过程中的动态演变规律以及疲劳裂缝的形成机理,推导出钢桥面沥青铺装层疲劳性能方程和车辆轴载换算公式.结合南京长江第二大桥钢桥面铺装工程,应用所建立的疲劳性能方程以及轴载换算公式对钢桥面铺装层使用寿命进行预测.
Abstract:
Basing on the method of approximate mechanics, the mechanical behavior and fatigue fracture characteristic of steel bridge asphalt mixture surfacing under repeated load was analyzed. Adopting the viscous-elastic method of energy conversion, the stress, strain and fracture distribution or evolvement rules of the composite structure of steel bridge deck asphalt mixture surfacing were explored. According to the dynamic evolvement rules of the stress, strain and fracture distribution or fatigue cracking mechanism, fatigue equation and axle load conversion of the steel bridge deck asphalt mixture surfacing are proposed. Finally, the fatigue equation and axle load conversion are applied to forecast the steel bridge deck pavement’s service life of Nanjing Second Yangtze River Bridge.
