Abstract
An approach to inspection of incipient faults in dam by non_d estructive testing is a so far emerging inspection technology in the world. In this paper, inspection principles, system integrity and key items of the new blasting source-based technology for inspection of incipient faults in dam, different from common non- destructive testing, are presented, following briefing experiences in dam inspection by elastic wave CT in recent years. Specific procedures and goals for further spreading and application as well as conclusion are introduced finally.
