IMPROVED SUBSURFACE INVESTIGATION FOR HIGHWAY TUNNEL DESIGN AND CONSTRUCTION. VOLUME 2. NEW ACOUSTIC TECHNIQUES SUITABLE FOR USE IN SOIL

The purpose of this study was development of new acoustic techniques suitable for use in soil. Primary consideration was given to determining the location of any rock that may be present between boreholes. A secondary objective was to investigate the potential of acoustic techniques for predicting variations of properties between boreholes. In pursuit of these objectives, the properties of the sonic spectrum in soil were investigated with application to locating discontinuities. A review of potential techniques for improving coupling to soils was also conducted.
