When the walls and floor of a tunnel are excited by a train, a ground vibration energy is transmitted to the surface and to footing of a nearby buildings. Excessive vibration affected to a building structure causes undesirable effect to the structural safety and the perception on residents in building. In this paper, a simple approach is introduced to predict how much vibration, in terms of level and spectra, is transmitted through the ground from the tunnel vibration excitation. A high rise building on a tunnel is selected as an application example of this case study.
