Abstract

Taking an urban rail transit elevated line as the engineering background, field measurements have been made on the acceleration of the semi-closed noise barrier when a train was traveling in straight and curved sections, and time history and spectrum analysis were performed on the measured data.Based on the theory of vehicle-line-bridge coupled vibration, by establishing a vehicle-curve bridge-noise barrier structure vibration analysis model, the accuracy of the model was verified by comparison with the measured data.Based on the simulation model, the influence of the curvature of the viaduct on train-induced vibration of semi-closed noise barriers was analyzed.The results show that: In the urban rail transit elevated line, the train-induced vibration response of the semi-closed noise barriers in the curved section was greater than that in the straight line segment.The dominant frequency band of the main lateral vibration is 70—140 Hz, and the peak value of the lateral vibration displacement is linearly positively correlated with the curvature.The fitting formula was obtained, and the vibration response of the semi-closed noise barrier on the viaduct with different curvature could be approximated.
