PROBLEM TO BE SOLVED: To provide a method for identifying the train vibration noise of a seismometer installed along the rail road in which the seismometer is installed along the rail road and the determination accuracy of the train vibration noise is enhanced based on an observed waveform of acceleration.SOLUTION: In the train vibration identifying method of a seismometer installed along the rail road, the seismometer is installed along the rail road, and by paying the attention to the fact that the seismic motion observed by this seismometer and the train vibration are different in dominant frequency bandwidth, the train vibration noise identification of the seismometer installed along the rail road is performed using high frequency sampling data with the seismic motion and the train vibration, respectively. In particular, R=high frequency component vertical motion acceleration absolute value/low frequency component vertical motion acceleration absolute value of the seismic motion and the train vibration is obtained, respectively. It is determined that R>α represents the train vibration and R<α represents the seismic motion. |
