SEISMIC REFRACTION SURVEYS FOR PREDICTING THE INTENSITY AND DEPTH OF WEATHERING AND FRACTURING IN GRANITE MASSES . FIELD TESTING IN ENGINEERING GEOLOGY. PROCEEDINGS OF THE TWENTY-FOURTH ANNUAL CONFERENCE OF THE ENGINEERING GROUP OF THE GEOLOGICAL SOCIETY, SUNDERLAND POLYTECHNIC, SEPTEMBER 4-8 1988

Seismic refraction surveys were employed for shallow investigations (down to 20-30 m depth) and conducted across the top of vertical exposures where the underlying geology could be directly inspected. The suitability of shallow seismic refraction surveys for identifying the intensity and depth of rock weathering and fracturing at the respective locations could thus be correctly assessed. Research completed on granites of Jurassic and Cretaceous age from Korea had previously indicated that these granitic materials could be divided with reasonable accuracy into five weathering groups using visual and simple mechanical techniques. Weathering boundaries determined by seismic refraction methods were found to agree within a 2 m variance with visible differences in weathering in the vertical exposure beneath each test site. The intensity of fracturing could also be predicted by seismic refraction surveys with relatively good accuracy. It was concluded that the field seismic survey method in shallow Korean granitic masses could be considered a very useful and cost-effective technique for assessing the intensity and depth of weathering and fracturing.(A) For the covering abstract of the conference see IRRD 832042.
