| Abstract: | The cause of crack formation in construction of prefabricated T beams of a certain prestressed bridge is analysed. Exact and quick diagnosing of cracks in concrete structure can be achieved using ultrasonic nondestructive testing technique of double elliptical location, and successful examples are given of determination of the crack depth of the T beams using the method. An economic and effective scheme for mending up of the cracks is put forward. The T beams which were mended up are in normal service. |
