Tomograph used corrected inversion method for concrete structure model using impact-echo method was tried. There are traveltime inversion method and full-wave inversion method on seismic data interpretation. The traveltime seismic method uses first arrival time which is calculated by ray method, finite element method, finite difference method and so on. Full-wave inversion is the best method in terms of model resolution and overcomes limitations imposed by the high-frequency restriction in traveltime inversion and the weak scattering approximation of Born methods. But this method have difficulties and weak points in accuracy and selection of intial velocity value. In this study, corrected seismic inversion method which is able to solve the above difficulties is applied to theoretical pier model to calculate tomography.
