Abstract The borehole ultrasonic imaging method can precisely reflect the smoothness of the borehole wall, and then judge the weathering degree of the rock and determine thickness of the weathering bed. This paper describes traveltime and amplitude image characteristics of borehole ultrasonic imaging, and gives an application example in Hong Kong area.
