A General Review on Mitigation Measures for Railway and Urban Rail Transit Vibration

This paper gives a brief introduction to the standard measurement methods of environmental vibration at home and abroad, and characteristics of railway environmental vibration in China. Various mitigation measures for railway vibration are presented in detail. They include vibration source control, route control of vibration transmission and vibration isolation measures for protected objects near rail transport systems. Vibration source control mainly con- tains vehicle vibration control, reducing the track irregularity and rail vibration control. Vehicle vibration control mainly indicates the design of light-weight vehicle, rational wheelbase, suspension system, and resilient wheel, damped wheel, wheelset-turning repair, and optimizing the dynamic characteristics. Track irregularity and rail vibration control are re- lated to the use of heavy rail, scientific strategies of rail grinding, treatment of rail joint and the use of damped rail. Route control of vibration transmission is involved in damping fastening, elastic pad, elastic damping sleeper, various vibration damping track structures and ground vibration isolation measures. The vibration isolation measures for the protected objects are mainly to consider setting their foundation isolation. The present paper provides the references and guides for how to choose mitigation measures for railway vibration.
