| Abstract: | In order to study the attenuation behavior of ground vibration under bridge caused by moving trains, a lot of ground acceleration data on the various train velocity are collected from series of in situ tests. The maximum acceleration values are obtained from the test data. Then compound regression method is carried out to study the attenuation empirical formula for ground acceleration under bridge induced by moving trains. |
