The Forward Simulation on Geometric Characteristics of Adverse Buried Bodies Using Ground Penetrating Radar

Adverse buried bodies near to ground surface would damage the buildings, and the detailed geometric characteristics of adverse buried bodies is essential for reducing damage and potential risk. To achieve this goal, forward simulation on geometric characteristics of three typical culverts in Chongqing were carried out in this paper. The response characteristics of (ground penetrating radar) GPR profiles caused by geometric characteristics and filling materials change were summarized, and the apexes of diffraction hyperbolas and lateral changes in the reflection pattern were used to determine the dimension and boundary of buried bodies. The comparison between GPR profiles interpretation result and the measured data in the field was used to verify the validity.
