Abstract:
Taking Wenzhou urban rapid rail transit project, the impact characteristics of operational vibration and noise on the environment is analyzed, and comprehensive measures for vibration and noise reduction are proposed. Source strength is controlled by vehicle selection, elevated section bridge beam type optimization, and high damping bearing selection, track vibration and noise reduction. Transmission is controlled by setting noise barrier. The planning of surrounding plots is adjusted and optimized and sound insulation of surrounding buildings is enhanced to further reduce environmental impact caused by noise and vibration. Practical application results show that the above comprehensive measures for reducing vibration and noise are concretely effective.
