摘　　要：正交异性钢桥面已在钢桥中大量应用,日益增长的车流量和超载车辆使得该类桥梁在较短的运营期内就出现了大量不同程度的裂纹,对桥梁的正常使用带来了极大的影响。本文通过有限元分析,对正交异性钢桥面板的局部构造进行超载和疲劳验算,以便对今后的工程设计起到指导作用。Orthotropic steel decks(OSDs) have been widely used in bridges, and different levels of cracking have emerged in OSDs with increasing traffic flow and overloaded vehicle, which greatly influences the service of the bridge. This paper analyzes the partial overload and fatigue of OSDs with the finite element method in order to provide guidance for the engineering design in the future.
