Application of GPR to detecting and mapping cracks in rock slopes

Multiconfiguration GPR measurements for geometric fracture characterization in limestone cliffs (Alps)

“…In a gypsum quarry, Dérobert and Abraham (2000) performed GPR profiles on pillars to characterize the crack depth and inclination, while damaged zones were imaged as low P-wave velocities by seismic tomography. Similarly, Toshioka et al (1995) detected the distribution and continuity of cracks from GPR data acquired on the vertical wall of a welded tuff rock. Seol et al (2001) developed a strike-direction-finding scheme using GPR data obtained from three different acquisition modes for the same survey line in a granite quarry.…”

Mapping of evaporite deformation in a potash mine using ground penetrating radar: Upper Kama deposit, Russia

“…The successful application of GPR to fracture detection and study of deformation in crystalline and sedimentary rocks is reported in numerous publications (Busby and Merritt, 1999;Grandjean and Gourry, 1996;Orlando 2003;Porsani et al, 2006). Grasmueck (1996), Lane et al (2000), and Toshioka et al (1995) described the usage of GPR for detecting and mapping millimetric cracks. A number of studies have demonstrated the enhanced capability of 3-D GPR imaging to delineate the subsurface structures (Christie et al, 2009;Grasmueck et al, 2004;Gross et al, 2003;Young et al, 1997).…”

Contribution of Ground Penetrating Radar and Electrical Resistivity Tomography to identify the cavity and fractures under the main Church in Botrugno (Lecce, Italy)

“…Geophysical survey has been applied in a variety of studies including: soils mapping, as well as engineering and geotechnical investigations [1,4,5,9,12,14]. However it is not always immediate to compare the results of these studies because of the different field conditions.…”
