Determination of Compressional and Shear Wave Velocity during Triaxial Compression: A Laboratory Manual.

摘要

The Naval Research Laboratory has modified a triaxial compression apparatus to include compressional and shear wave transducers for the purpose of measuring changes in compressional and shear wave velocity during consolidation. This report specifies the procedures and equipment used for this purpose. In general, the procedures are those required for a standard triaxial compression test with the following exceptions: (1) the additional steps required to obtain velocity data are included and (2) detailed procedures for shearing the sample have been excluded since determining shear strength is not our primary objective, although the modified apparatus can still be used for this purpose.
