摘    要:借鉴了路面平整度的概率模型,提出了桥面破损激励下的计算模型,并建立了车桥耦合振动方程。通过对16 m简支梁桥在桥面破损的影响下进行了动力效应计算,分析了桥面破损激励对车桥耦合系统的影响,讨论了公路桥梁结构的动力效应随车辆行驶速度、桥面破损位置的变化而呈现的变化规律。

关 键 词:车桥耦合振动  桥面破损  动力效应  分析

Abstract:In this discussion,on the basis adopting the probability model of the road surface roughness,the suppuration model of the damage of bridge-deck is built,and the vehicle-bridge coupled vibration equation under the influence of the random factors are also built.Respectively calculates the dynamic effect of 16m bridge on the aspect of the damage of bridge-deck are discussed and the law of vehicle-bridge coupled system under the influence of the damage of bridge-deck are analyzed.The changing law of vehicle-bridge coupled system under the influence of vehicle's speed or the physical location of the damage of bridge-deck on the bridge are proposed.
Keywords:vehicle-bridge coupled vibration model  damage of bridge-deck  dynamic effect  analysis
