| 英文摘要 | A running high-speed-train can cause vibration of rails, generating seismic waves to propagate in the subsurface. Geological conditions along a railroad can be continuously monitored by studying such seismic waves. Compared with conventional seismic exploration, the source of high-speed-train induced seismic waves, a moving one, is more complex. The seismic interferometry can eliminate the influence of the source through the interference between seismic records. Therefore, this method can be used to process high-speed-train seismic signals and image subsurface structure. This paper summarizes the key technical problems of seismic interferometry in this aspect. Unlike conventional seismic interferometry, the moving source of the high-speed-train makes the interference sequence superimposed first and then interfered, which brings in a lot of source crosstalk noise. Two solutions to this issue are put forward preliminarily: the high-speed-train can be "accelerated" or "decelerated" in a disguised form by processing the signal of high-speed-train seismic waves, and the ideas on imaging after "acceleration" or "deceleration" and the technical approach of data processing are proposed, respectively. |
