摘　　要：在工程勘察中,岩(土)层的动弹模量等弹性参数反映了岩(土)层的相对强度,能够为建筑设计提供一定的参考依据。声速测井除了能够计算各种弹性参数外,还能够进行岩性划分、圈定岩体氧化带、解释软弱夹层等,在工程勘察中发挥了重要作用。结合实例,介绍了声速测井在工程勘察中的应用效果。In the geotechnical investigation and surveying, some elastic parameters,including the modulus measurements of rock layer and so on,have reflected the relative intensity,which can provide reference evidence for the architectural design. Acoustic velocity logging can carry on the lothological determination,delimit oxygen belt of the rock mass and explain soft intercalated layer and so on, as well as calculating all kinds of elastic parameters. It plays an important role in the project exploration. This paper introduced the application effect of acoustic velocity logging in project exploration with examples.
