An Investigation Of Cracks In Rock Slope Using Ground Penetrating Radar

Rock slope collapse is an important problem in road maintenance works. Earlier investigations in collapsed<br>rock slope suggest that the internal structures of the cracks are important in forecasting rock collapses. Various<br>geophysical exploration methods may be applied in cases when visual inspection alone dose not provide sufficient<br>information. Recognizing the high resolution capability of ground penetrating radar (GPR), a site experiment was<br>conducted on a vertical wall of welded tuff in order to determine the applicability of GP to substance crack investigations.
