Abstract

In order to study the vibration characteristics of tunnel invert and tunnel invert filling，in-situ train induced vibration tests were performed in the second railway line of Lanzhou-Xinjiang.Attenuation and distribution laws of the vertical vibration acceleration in the tunnel invert and tunnel invert filling under different speeds and depths were Analyzed,and compared the results with numerical simulations.The analytical results indicate that with the certain speed,the vertical vibration acceleration response value decreases with the depth in a fast attenuation rate on the trains running side.The vertical vibration acceleration response value increases when the train running on double lines at the same time compare with running on a single line.Increased degree is related to the train running speeds.Numerical simulation results agree well with field tests results.Tunnel invert and its filling are the main carriers of bearing vibration acceleration,which should be the key point in design.The results have important significance for optimizing the supporting system of tunnel and ensuring train running safety.

Key words
