Abstract

Determining a bridge structure's existing conditions and load carrying capacity often requires more complete data than can be gathered by visual observation and simple measurements. This is true below water as well as above. Various nondestructive testing techniques may be utilized underwater to gather such detailed data. Techniques to be addressed in this paper include ultrasonic nondestructive testing of timber and correlation to destructive and partially destructive testing, pulse velocity of concrete, ultrasonics in steel inspection, and an example of the underwater usage of diver-carried ground penetrating radar.
