And the measurement of Vs is a critical task in the solution of geotechnical earthquake engineering problems. In this study, piezoelectric bender elements were used to measure the shear wave velocity on reconstituted specimens of soft Macao marine clay. Various initial stress conditions, including isotropic and various stress ratios, η, were simulated in the triaxial apparatus. Two signal interpretation methods, the characteristic peaks and the cross-correlation, were used to determine the travel time for calculation of the shear wave velocity. In addition, void ratio functions were assessed, and empirical correlations between the maximum shear modulus and the initial stress condition as well as the void ratio were proposed for Macao marine clay.
