摘要：A section of the subway viaduct is taken as the subject investigated, the acceleration of piers and ground are monitored when the train pass through. The vibration characteristics of elevated rail transit pier and adjacent ground are studied. Through the fitting of the monitoring data, the empirical formula of the building vibration is obtained in the vertical direction with different source distance under the standard working condition. The results show that the pier vibration caused by the operation of the elevated rail transit is mainly in the direction of the train operation. In the process of vibration propagation from the top to bottom of pier, vibration attenuation is larger due to the inlay effect of the foundation. The vertical vibration of the building decreases with the increasing of the distance from the pier due to the attenuation in the soil. Comparing the vibration prediction model with the home-abroad representative model, the curve of model is similar. The prediction model provides reference for the building vibration prediction near the elevated transit.
