Prediction of Vibration Response of Buildings Induced by Subway Operations
Translated Abstract
Two models were established for analyzing the vibration responses of buildings adjacent to Fuzhou Metro. One of them was for numerical analysis of vehicle-track coupled vertical vibration, and the other was the tunnel-soil-build-ing coupled model of 3D FEM. In reference of the vibration source parameter of Fuzhou metro and typical in-situ soil distri-bution of kind II along the Metro line, vibration responses of buildings adjacent to the Metro induced by the subway opera-tion were predicted. The results show that the vibration responses of the adjacent buildings are mainly the medium and high frequency vibrations, and the dominant frequencies of the floors are the natural frequencies of the buildings. Meanwhile, in the lower floors there exist medium-and-high frequency rebound areas due to the excitation. Speed and single-or-double track traveling of trains have no influence on the vibration type of the buildings, but have significant effects on the vibration acceleration level of the floors. When the horizontal distance from the multistoried or middle-highrise building to the center-line of the subway are smaller than 10m, or the distance for highrise building is smaller than 15m, and the train speed ex-ceeds 40km/h, the vibration acceleration levels of the floors may exceed the standard vibration limit. In this case, measures for vibration control should be considered.
