COMPARISON OF OBSERVED RESISTIVITY MEASUREMENTS TO CONSTRUCTION PROJECTS

A PROGRAM WAS INITIATED IN SOUTH DAKOTA IN 1966 TO STUDY DATA IN THE FILES WITH REGARD TO THE RELATIVE SIGNIFICANCE OF INFORMATION DERIVED FROM RESISTIVITY SURVEYS IN REGARD TO MATERIAL EXCAVATION ESTIMATES. OBJECTIVES INCLUDED A DETERMINATION OF THE RELATIVE ACCURACY AND COST OF THE METHOD AS COMPARED TO CONVENTIONAL DRILLING TECHNIQUES, AND CONSIDERATION OF POSSIBLE IMPROVEMENTS IN FIELD PROCEDURES AND EQUIPMENT AND IN DATA INTERPRETATION. RESISTIVITY DATA INVOLVED FOUNDATION STUDIES, GRAVEL LOCATION AND HARD ROCK ESTIMATION. THE TEST WAS FOUND TO BE EFFECTIVE IN ITS APPLICATION TO ALL THREE PROBLEMS. IN GENERAL, THE COST OF A RESISTIVITY SURVEY MAY VARY FROM 15 TO 75 PERCENT OF THAT INVOLVED IN DRILLING. THE WENNER FOUR-ELECTRODE CONFIGURATION AND THE MOORE CUMULATIVE CURVE TECHNIQUE FOR DATA INTERPRETATION WERE FOUND MOST USEFUL IN SOUTH DAKOTA. /AUTHOR/
