Application of BGPR Logging: Two Case Studies

Abstract

In this paper, two Taiwan case studies are used to investigate the potential application of the borehole ground-penetrating radar (BGPR) technique. The first case located an unknown buried pipe which had to be dug out prior to underground excavation work. The second case identified the existence of reinforcing bars inside the foundation piles. These missing reinforcing bars potentially threaten the safety of a planned bridge. The results of these studies clearly demonstrate the capability of BGPR to effectively identify the existence of underground targets and thereby provide necessary information for engineering work.
