摘要：

Comprehensive tests performed in a large calibration chamber and consisting of the propagation of seismic body waves in dry Ticino silica sand are presented. By virtue of the fact that both shear and constrained compression waves have been propagated in vertical, horizontal and oblique directions, five independent constants of the cross-anisotropic elasticity model of the test have been established. The tests have also made it possible to evaluate the influence of the structural (inherent) and stress-induced anisotropy on the velocity of the propagated seismic body waves. The influence of the principal effective stresses on the velocity of these waves is also described.
