Research purposes:Vibration and noise pollution caused by urban mass transit is increasingly becom ing a prominent problem, so it is necessary to pay attention to them. Therefore, the design of reducing noise and vibration based on the environmental assessment report and the actual engineering is very important. This paper, combined with the east extension project of Line 2 of Shanghai Metro, puts forward the new design concept on and the engineering measures for reducing the track vibration and noise of urban mass transit through the research and analysis.
Research conclusions:The research results show that the reasonable choice of track structure and structural parameters are the main measures for reducing the vibration and noise, the stiffness design of the track structure is the focal point of track design, and research and development of vibration and noise reducing track structure is the development direction in future.
