The invention discloses a ballastless track disease rapid identification method based on wheel track noise and vibration waveform, and the method comprises the following steps: S1, collecting vibration data with the frequency of 0-2500Hz in a ballastless track structure, and enabling the vibration data with the frequency not exceeding 400Hz to correspond to the vibration frequency of a ballastless track bed; the vibration data in the range are stored in a mode of converting vibration waveforms into pictures; the vibration data exceeding 400 Hz correspond to the wheel track noise audio frequency, and the vibration data in the range are stored as noise audio characteristic data; s2, respectively establishing a wheel track noise audio database and a ballastless track bed vibration waveform picture database through long-term monitoring; s3, performing similarity analysis on train wheel track noise audio data and ballastless track bed vibration waveform data which are acquired in real time and a database establish
