Abstract: Based on the propagation theory of ultrasonic in the concrete,a theoretical model employed in the testing of damage in the concrete structure have been presented in this paper.The calculation results of the models indicated that the theoretical modeling has good resolution ration and anti disturbance power.

Key words: ultrasonic, tomography, the concrete sturcture, testing of damage
