Abstract

At present, there is no systematic research on the ground surface vibration bounce area induced by metro. The experiments of vibration attenuated on the ground surface were carried out in an underground laboratory at Beijing Jiaotong University to obtain the ground surface attenuation characteristics of vibration in 0~200Hz. The automatic falling weight device was designed for exciting a wide band vibration in the experiments. Vibration measurements were performed on the ground surface at distances varying from 0 to 60 m from the track at every 5m. Detailed results indicates that the attenuation of different single frequency acceleration peak value envelope decays wavy-type with peaks and valleys, and the attenuation of each single frequency is not the same. The ground surface vibration bounce positions depend on the main vibration frequency band of the vibration source and the propagation characteristics of the stratum.
