Abstract
In this study, the elastic properties of loose to medium dense (Dr=50%) sandy soil were obtained from elastic wave propagation techniques in the laboratory. The soil specimens were assumed cross anisotropic medium. Two bender elements are embedded in the top cap and the pedestal of the triaxial device as receivers and transmitters in the vertical direction for P- and S-waves. In addition, two bender elements are attached to the membrane surrounding the soil specimen to measure horizontal P-wave velocities. After the preparation of the specimens, vertical and horizontal P-wave velocities and a vertical shear wave velocity were measured under different effective confining pressures. Numerically 5 independent elastic parameters of cross anisotropic soil samples were recovered. In terms of the anisotropy parameter (α), modified Young’s modulus (E*) and Poisson ratio (ν*).
