The full waveform inversion technique needs low frequency data to ensure its stable convergence. Therefore, it has an advantage to use this signal to perform full waveform inversion for near surface modeling. Based on the characteristics of repeatable signals of high-speed train, uses times-lapse technology to realize geological hazard prediction. In this paper, the theoretical wavelet signal and discrete wavelet signal based on pier are studied. The model test shows the attribute change from different monitoring data.
