When the train runs along the railway line, the vehicle-track system vibrates due to the wheel-rail dynamic load excited by the track irregularity. The vibration propagates in a radiative manner to the distance of the earth through the ballasts and the subgrade, which makes the buildings near the railway vibrate. This kind of vibration will have a great impact on the normal work and health of people, the safety of building structures and the use of some precise instruments and equipment. Therefore, in order to control the negative impact of rail transit on the environment, it is urgent to study the occurrence mechanism of environmental vibration caused by rail transit, the magnitude of wheel-rail interaction force and the law of vibration propagation and attenuation, and put forward corresponding vibration isolation measures. In this paper, the vibration control effect of surface structures is studied on rail transit under different vibration reduction measures.
