Title: GEOPHYSICAL METHODS OF SUBSURFACE EXPLORATION APPLIED TO MATERIALS SURVEYS
Accession Number: 00229578
Record Type: Component
Abstract: GEOPHYSICAL TEST METHODS, THE REFRACTION-SEISMIC AND THE EARTH-RESISTIVITY, ARE USED FOR SHALLOW EXPLORATION AND ARE ASSOCIATED WITH CIVIL ENGINEERING WORKS. A LIMITED DESCRIPTION IS PRESENTED OF THE PRINCIPLES INVOLVED IN THESE TWO METHODS. BOTH TESTS ARE CAPABLE OF PROVIDING DEPENDABLE INFORMATION WHEN USED IN SUBSURFACE EXPLORATION STUDIES. IT IS CONCLUDED THAT THE EARTH-RESISTIVITY TEST IS PROBABLY THE BETTER OF THE TWO METHODS IN THAT IT IS FASTER AND HAS WIDE APPLICATION TO ALL OF THE PROBLEMS INVOLVING THE SHALLOW TESTS. THE SEISMIC REFRACTION TEST IS OF GREATEST USE TO LOCATE A RIGID, DENSE MEDIUM, SUCH AS SOLID ROCK. BOTH METHODS MAY BE USED JOINTLY TO EXPLORE A GIVEN SUBSURFACE CONDITION. THE SEISMIC TEST IS BEING USED TO OBTAIN A RAPID CHECK ON THE ACCURACY OF THE INDICATIONS FROM THE RESISTIVITY SURVEY.
