| Abstract: | For the seismic source generated by the high-speed rail with viaduct, a theoretical method is proposed to measure the apparent velocity of the high-speed rail wavefield generated by a moving source set by using cross-correlation of the waves recorded by multiple stations. Furthermore, synthetic data of the high-speed rail wavefields in layered media is generated, and the apparent velocity of a phase in it is calculated. The correctness of the method is verified compared with the theoretical results. |
