///Information and 3-D images for attitudes of layers have been got with ultrasonic borehole televiewer (BHTV) in geotechnical investigation. Borehole information of rock mass fractures in seven drillholes was derived by BHTV in a underground oil storage cavern. It includes scatter plots of poles and rose maps of dip direction for structure plane with depth, dip direction, strike direction, integrality and line intensity of jointing, 3-D core images, 3-D borehole wall images, joint pole maps and rose maps of jointing. The statistical characteristics of these maps and images are analyzed. The results reveal that BHTV is a valuable tool for geotechnical investigation.
