Sample Coupling in Resonant Column Testing of Cemented Soils


Low-strain shear moduli of lightly cemented sand can be obtained by testing specimens in a resonant column. In the literature a variety of techniques have been suggested for coupling the sample to the base and cap of the device. These studies' results suggest that the shear modulus of cemented sand changes with confining pressure. In this study, the specimens were coupled to the end platens with epoxy which was allowed to harden before testing. The results indicate that the low strain shear modulus of lightly cemented sand is nearly independent of confining pressure for pressures up to 500 kPa. The difference in the effect of confining pressure on the shear modulus, in this and other studies, is attributed to the different coupling techniques used. The results illustrate the need for a rigid connection between the specimen and the end platens.
