%X Acoustic logging and wave velocity measurement of borehole cores are applied to get some important information about rock characteristics in Nanjing subway engineering investigation. Based on the comparison of physical properties between acoustic logging and borehole cores,using the synthetical analysis of multi- parameter,much efficient information about rock weathering and strength is achieved. Using rock acoustic wave velocity of in-situ measurement,the distributing characteristic of the wave velocity of rocks in different depths are presented. Compared with the velocity measurement of well-logging and borehole cores,the disparities of rocks with different strengths on different measuring conditions,the amplitude variation,and attenuation characteristics of wave features of well-logging,are analyzed,and the structure properties of the rocks are discussed. It is proved that acoustic logging is a rapid,economic,and efficient method on in-situ measurement in geology engineering investigation.
