In this paper, for this type of bridge, the dynamic time-history analysis method is used to analyze the seismic response of bridge under uniform excitation and traveling-wave effect. The focus is on a three-span highway bridge with unequal height piers crossing a mountain valley. Group pile effect and soil-structure interaction being taken into account, the bridge and its foundation system, including the surrounding soil, are modeled by finite elements. The analyses show that traveling-wave has strong influence on response of earthquake, and the relative displacement of top and bottom of low pier is less sensitive to traveling-wave velocity than that of high pier. Due to traveling-wave effect, the maximal moment at top of low pier is much larger than that of high pier, but its variation is less than that of high pier with the change of wave velocity. The effect of soil-structure interaction being taken into account, decrease of whole stiffness of structure results in that the frequency of vibration reduces and relative displacement of top and bottom of pier increases.
