| Research Abstract |
In this research, application of the microtremor monitoring as a health monitoring of a ground is considered focusing on the variation of the shear wave velocity of the ground due to the variation of the ground conditions such as water content in the ground. However, in a field measurements, noises from neighborhood factories or something was one of the sever difficulties in practice. Then, application of not a small signal in microtremor but a larger signal induced by artificial vibration in multichannel surface wave method is focused. In practice, the research team succeeded to observe the variation of ground water level in a quay wall due to the tidal effect.
