Abstract borehole acoustic testing is an important in situ geotechnical engineering geophysical testing project. But during the test and test methods and equipment layout parameters selection, elastic wave identification, integrity coefficient calculation, and test results of engineering applications, such as wave column contains geological information and the application of the wave velocity and integrity of the relationship, testers not easy control and very questionable. Therefore, it is necessary, the above problems are discussed, with wants to improve investigation technology level.
