The Use of Ground Penetrating Radar for the Detection and Study of a Buried Marble and in Situ Location of Possible Cracks

摘要

This work described the use of two methods to detect possible abnormalities, debris and cracks inside block of marble. The first method was based on the direct detection of block of marble buried at depth of 0.2 m using Ground Penetrating Radar (GPR). The second method w as based on the use of simulation software named GprMax2D for the same block but at depth of 0.5 m. Our results showed that GPR technology combined with adequate simulation software may be used in the field of exploitation of marble in specialized careers. Indeed, they allow in situ distinguishing between usable blocks of marble with higher quality and blocks w ith fractures or leftover debris in their interior
