Analysis of the Vibration and Secondary Structural Noise of Buildings above Subway
Aiming at the vibration and the secondary structural noise of the buildings above subways when which are on operation , a train-track-tunnel-soil-building interaction numerical model was es -tablished to investigate the vibration of these constructions and the secondary structural indoor noise. Based on the engineering application , the noise-reducing effect of the three types of track commonly used in subway was compared. The Low Vibration Track(LVT)performs better in reducing the VLz of buildings and the secondary structural indoor noise than the ordinary monolithic track,but not as well as the Floating Slab Track (FST) ,which approximately reduces the secondary indoor noise by 10dB(A).
