Abstract
Measurements of shear wave velocities, Vs, during triaxial compression tests were conducted on undisturbed samples obtained from a diluvial gravel deposit. The reconstituted gravel samples were also tested to compare the characteristics of shear wave velocity. The results of these measurements indicated that Vs increases at the initial stage of the triaxial compression tests, and decreases gradually until the failure of specimen and that the reduction in Vs was more noticeable for the undisturbed samples than for the reconstituted samples. The results also revealed a unique relationship between Vs when evaluating the effect of stress ratio and confining pressure for both undisturbed and reconstituted samples at failure. Index of shear wave velocity is introduced to express uniquely the change of Vs in both undisturbed samples and reconstituted samples during triaxial compression tests.
