USES OF GEOPHYSICS IN SUBSURFACE SURVEYING

THE MICHIGAN DEPARTMENT OF STATE HIGHWAYS MAKES EXTENSIVE USE OF GEOPHYSICS FOR SUBSURFACE SURVEYING WHICH WOULD BE APPLICABLE FOR USES IN OTHER FIELDS. EXAMPLES OF RESISTIVITY SURVEYS ARE GIVEN WHICH INCLUDE A PROPOSED LARGE-VOLUME EXCAVATION WITH SUGGESTIONS FOR LAND USE AFTER EXCAVATION, SUBSURFACE EVALUATION FOR ENGINEERING DESIGN, AND A SUBSURFACE SURVEY FOR LAND APPRAISAL. AN EXAMPLE OF A COMBINED REFRACTION SEISMIC AND RESISTIVITY SURVEY IS SHOWN WHERE THE RESISTIVITY IS USED TO OUTLINE UNCONSOLIDATED SOILS, WHILE THE SEISMIC METHOD IS USED TO OUTLINE BEDROCK AND TO EVALUATE IT FOR RIPPABILITY. A REFRACTION SEISMIC SURVEY AT THE BOTTOM OF BRIDGE CAISSONS FOR EVALUATION OF BEDROCK UNIFORMITY AND A RELATIVE AID IN ASSESSING ROCK STRENGTH IS REPORTED. /AUTHOR/
