| 摘 要： | 借鉴了桥面平整度的概率模型，提出了桥头跳车激励下的计算模型，并建立了车桥耦合振动方程。通过对30m简支梁桥在桥头跳车的影响下进行了动力效应计算，分析了桥头跳车激励对车桥耦合系统的影响，分别讨论了桥梁结构的动力效应随行车速度、桥头高差的变化而呈现的变化规律。

| Abstract: | On the basis adopting the probability model of the bridge surface roughness,the suppuration model of the vehicle＇s bridgehead jumping is built,and the vehicle-bridge coupled vibration equation under the influence of the random factors are also built.In this paper,it calculates the dynamic effect of 30m bridge on the aspect of the vehicle＇s bridgehead jumping,and the law of vehicle-bridge coupled system under the influence of the vehicle＇s bridgehead jumping is analysed.At last,the changing law of vehicle-bridge coupled system under the influence of vehicle＇s speed or the height between the bridge surface and the road surface on the bridgehead are studied. |
