The invention discloses a settlement monitoring method for a high-speed magnetic suspension track, which comprises the following steps of: extracting a communication signal power value of an existing high-speed magnetic suspension millimeter wave communication system in the running process of a magnetic suspension train, drawing a receiving power curve of a line, and detecting the settlement condition of the track by analyzing the change of the receiving power curve. And a settlement value is extracted by utilizing the offset of the wave crest and the wave trough to realize track monitoring. The method is based on a double-path propagation model in wireless communication and depends on an existing high-speed magnetic suspension millimeter wave communication system, the problems that an existing track monitoring method is complex in operation, poor in real-time performance and the like are solved, the problems that a modern track monitoring technology is high in cost and many in environmental limitation are solved, the method can serve as a powerful supplement of an existing monitoring system, and the method is suitable for popularization and application. The method is suitable for high-speed magnetic suspension tracks, is also suitable for high-speed railways, common railways, even low-speed railways and other scenes needing track settlement monitoring, and has the advantages of being good in real-time performance, wide in measurement range and low in cost.
