Mapping Fractures in Vertical Rock Cuts using a 400 MHz Ground Penetrating Radar Antenna
Parallel to sub-parallel hidden discontinuities to the slope face of a sandstone bedrock were effectively mapped at four different stations in central Missouri using a continuous-distance-mode ground penetrating radar system equipped with a 400 MHz monostatic antenna. At each station, a suite of 2-D ground penetrating radar profiles were acquired along multiple closely spaced traverses. A small wheel was appropriately and significantly attached to the used antenna to fit with the distance mode that was used in our GPR common offset survey. The exposed rock surfaces were relatively smooth which help to place directly the used attached-wheel 400 MHz antenna on the slope face of the bedrock and record the data effectively.
