Abstract

Structure health monitoring system is used to monitor structural responses in real time. Dynamic performances of subway station structures are help to analyze seismic performances of the structures. Through structure health monitoring system of a subway station structure, dynamic responses of the subway station structure were tested under railway loads. The dynamic strain and internal forces of subway station structure are obtained. As restrained by earth, dynamic responses of the subway station structure is not significant change from most surface structures. Wavelet and multiscale analysis can be a powerful tool for multiple decomposition of potential fields data. Wavelet analysis can eliminate the noise for a clear data. The main train induced vibration frequency is also acquired through the method of wavelet analysis.
