Vibration Impact of Freight Train on the Tunnel Base Rock Mass,lied on the sleepers. The results showed that the rock mass within 6.8?m away from tunnel invert was obviously influenced by the train vibration load. But to the rock mass just under the center of tunnel invert, the range of influence was expanded to 10?m. The rock mass out of the above range was less impacted by the freight train load.

Field Test and Analysis on Subway Train Induced Vibration,es an important issue. This paper introduces a field vibration test on Ningbo subway tunnel at different spots of track slab and tunnel lining, compares the vibrating performance at different spots. Then the propagating and damping properties of vibration are analyzed.

Establishment of Finite Element Model for Wide Steel Box-Girder Bridge by Modal Test, are carried out based on the field ambient vibration, stochastic subspace identification and peak picking of the average normalized power spectral densities are used to identify the bridge’s dynamic characteristics. Numerical simulation compared with the test result shows that the FEM established in this paper is quite accurate.
