The Application of Two Dimensional Numerical Simulation Method of Ground Penetrating Radar in Concrete Dam Nondestructive Testing

Abstract:

electromagnetic wave theory was used by ground penetrating radar, the defects in concrete dams were judged according to the measured concrete reflection waveform, frequency and wave velocity. The working principle of ground penetrating radar and numerical simulation process based on the finite different time domain method were studied, cracks, voids images in concrete was forward simulated by the above method. It was important to determine the quality defects in concrete.
