The invention belongs to the technical field of aircraft static strength test strain gauge measurement abnormal data correction, and particularly relates to an aircraft static strength test strain gauge measurement abnormal data interpolation correction method. Performing standardization processing on the coordinate values of the strain gauges and the previous measurement data, identifying abnormal values in the real-time measurement data of the strain gauges, and identifying the strain gauges adjacent to the strain gauges with the abnormal values as the real-time measurement data on the basis of a machine learning method. According to the method, the coordinate values of the adjacent strain gauges, the previous measurement data and the real-time measurement data are fitted, then the correction value of the abnormal real-time measurement data is obtained, convenience and rapidness are achieved, and in the static strength test of the airplane, the situation that the abnormal measurement data of the strain gauges disturb analysis of the stress condition of the airplane structure and prediction of dangerous parts can be avoided.
