The invention relates to a detection method of a turbine generator bearing bush with a dovetail groove, which is designed for improving the accuracy of detection results. The detection method comprises dovetail area detection and non-dovetail area detection, wherein the dovetail area detection method comprises the step of judging that an alloy layer has a lamination defect if secondary reflection wave is higher than 50 percent; and the non-dovetail area detection method comprises the steps of adopting a waveform comparison to perform bearing bush detection if the thickness of bearing bush Babbitt metal steel is smaller than or equal to 8 mm; and judging the quality of an interface through the wave amplitudes of a reflected wave of the interface and a bottom wave of a base material if the thickness of the bearing bush Babbitt metal steel is greater than 8 mm. The detection method is simple to operate and accurate in detection results.
