The invention relates to a novel corrugated pipe vibration testing and deformation cause evaluating method. The method is characterized by comprising the following steps that (1) a novel corrugated pipe vibration testing method is adopted to obtain vibration signals reflecting current operation states of corrugated pipes; in corrugated pipe vibration testing, vibration sensors are arranged at the mutually-perpendicular effective positions of the identical axial cross sections in the radial directions of the corrugated pipes and the axial positions of the corrugated pipes, and the vibration signals reflecting the current actual operation states of the corrugated pipes are obtained, wherein the vibration signals are collected by the sensors in the X direction, the Y direction and the Z direction; (2) spectral analysis is conducted on the vibration signals obtained through point measurement, and corrugated pipe vibration and deformation situation analysis is achieved. By the adoption of the method, corrugated pipes having deformation phenomena can be evaluated, deformation causes of the corrugated pipes can be found out, and technical support and a solution are provided for technical modification of the corrugated pipes.
