Abstract

Non-destructive testing (NDT) is the major method for inspecting material defects. However, the NTD using ultrasonic, radiographic, or Impact Echo method cannot accurately detect the inner defects of huge structures, such as a dam. On the other hand, elastic wave tomography, a non-intrusive geophysical technique, can generate a cross sectional picture of an object. With properly-set parameters and geometries of the elastic wave tomography, the inner defects or material properties of a dam can be detected reliably.
