查询词典 box bridge

When train running on the track, there has interaction between whiles and track, and the track will bend because of the weight of wheel. The bend wave will propagate to box-beam and further to bridge pier. Then the vibration propagate to around soil through the bridge pier, which can cause the second vibration on buildings.
