Abstract
In order to make full use of the surface wave information in high-speed rail seismic signals, this paper applies the two-station method and the rotation method to the high-speed rail seismic simulation results, trying to obtain dispersion curves of the fundamental-mode Rayleigh and Love waves. By analyzing the interference characteristics of the wave field generated by the piers of the high-speed rail with viaduct, we propose a surface-wave phase velocity correction method suitable for the high-speed rail seismic wave field. Numerical tests show the effectiveness of the method.
