In this paper, the dynamic response analysis of long-span continuous bridge under earth- quakes and train loadsimultaneously were performed. In order to considerthe coupled vibrations of ve- hicles and highway long-span continuous bridge, a numerical modelinvolving soil foundation under inclined seismic wave was established using finite element software. The dynamic response ofthe bridge withdifferentincidenceangles of seismic waves and the differenttrain speedswere calculated and ana- lyzed.The results show that seismic waveincident angles have a significant effect on the dynamic res- ponseof the bridge, and with the increasing of the incident angle, thevertical displacements, velocity and accelerations of mid-spanconstantly increase. While thetrain speeds have a slightly effect on the dynam- ic responseof the bridge under earthquake, and the dynamic responseof the bridge reach maximum at a certain speed.
