Abstract:

In order to assess the effects on the tunnel structures of metro line 2 due to the vibrations induced by the underground trains on the Diameter line which connects two of the biggest railway station in Beijing, a standard of vibration assessment is presented in this paper. The standard is based on the theory of the fatigue damage in the concrete structure due to the application of vibrations. Moreover, the influence of the underground environment on the tunnel structures is also considered, and some standards of vibration assessment in China and other countries are referred in this standard.

Key words: tunnel  , vibration  , standard  , fatigue damage
