To explore the vibration and noise characteristics of high-speed railway track box girder structures using different track types, the paper establishes a coupled dynamic model of high-speed train-ballastless track elevated- box girder through finite element method and multi body dynamics, and studies the structural dynamic response of trains, tracks, and box girders when trains pass at high speeds. And establish a boundary element model to explore the noise characteristics of the structure when laying different types of ballastless tracks on elevated box girders. The results show that when the train passes through the laying of Type III plates and double block elevated box girders, the maximum wheel load reduction rates of the train are 0.0 536 and 0.1 657, respectively, and the bridge deflection is 1/9 673 and 1/8 457, respectively. The vibration displacement of the track plate and base of Type III plate is smaller, and the vertical vibration transmission rate of the track box beam structure is smaller, resulting in better vibration reduction performance. The noise characteristics of elevated box girders using two types of track structures have little difference at the far point below the bridge, with peak frequencies of 31.5Hz; However, there is a significant difference under the bridge, with a peak frequency of 63Hz for the Type III plate and 20Hz for the dual block type, but the peak difference is very small. And the total sound pressure level of the box beam noise
