摘要
以某主跨436 m中承式钢桁拱桥为例,运用桥梁结构动力学与车辆动力学,将列车-桥梁视为联合动力体系,建立了列车与大跨度钢桁拱桥的车桥耦合动力分析模型,计算与分析了该桥列车通过时的桥梁动力响应和列车走行性。研究结果为大跨度钢桁拱桥的动力设计提供了理论依据。
A Xinjiaomen bridge was taken as an example which is a half-through steel truss arched bridge with a main span of 436 m,regarding the vehicle and the bridge as a combined vibration system,a vehicle/bridge interaction model were established with the application of bridge structural dynamics and vehicle dynamics.The bridge dynamic response and train running performance were calculated and analyzed indetail when train was passing the bridge,and the analytical results provide a theoretical basis for dynamic design on extra large long span steel truss arch bridge
