摘要：	A system consisting of modern electronic hardware and software technologies has been developed to perform rapid and automated inspection in order to detect an incipient failure in a major structural component of a bridge. The hardware includes piezoelectric sensors and data collection, processing and display devices. The techniques developed utilize methodologies of digital signal processing, linear control theory and pattern recognition, a branch of the artificial intelligence discipline. The system can be mounted inside a motor van which will function as a mobile laboratory for bridge inspection. With appropriate training, technicians should be able to operate the system routinely. The system is ready for field application and it is recommended that its potential be utilized. To enhance its capability especially to find the location of a crack, the presence of which has been detected, further research is also recommended.
