Abstract | A laboratory true triaxial box with individually applied stress system is used to model the in-situ
cross-hole and down-hole seismic tests, and hence determine the small-strain shear modulus and damping ratio,
i.e. Gmax and Dmin. The method suggested by ISSMGE TC10 in finding the S-wave arrival time is found to yield
consistent results when compared with the one obtained by the cross-correlation peak of two receiver signals.
The spectral ratio method integrated with the self-healing technique gives similar damping ratios as in resonant
column tests under isotropic confinement. Experimental results provide further evidence that shear modulus
is only dependent on the principle stresses in the direction of shear wave propagation and polarization. The
damping ratio, however, is independent of the principle stress changes, regardless of its direction with respect to
the polarization plane. The cross-hole test yields better results than down-hole test in this laboratory modeling. |
