Abstract：Aiming at the security，utilization，detection accuracy and other issues in the process of application and detection of wire rope，related research results of present nondestructive flaw detection of wire rope at home and abroad were analyzed comprehensively and the future trend of research was summarized. Firstly，the application of the nondestructive flaw detection in practical project was introduced，two kinds of specific technical characteristics of mainstream detectors were compared and analyzed，which were used in bridge construction and other industries.Then，the non-destructive testing technology's development was introduced，the detection technique of

wire rope and the research on nonmagnetic detection technique as well as its application status were focused on. The magnetic detection techniques includes electromagnetic and permanent magnet law，non-magnetic detector includes current testing method，acoustic emission and sound - ultrasonic testing method.Finally，after comparing the research methods of present nondestructive flaw detection，the feasible method for concentrated nondestructive flaw detection of wire rope was proposed.The results indicate that the trend is to develop soundultrasound detection technique.
