The natural soils were deposited in successive layers during thousands of years. They develop different horizontal and vertical shear strengths, characteristic of their in-situ anisotropic behaviour. This article describes the anisotropy of the mechanical properties of resistance and deformability of a normally consolidated soft clay, based on the standard triaxial test results. The results presented highlight the anisotropic character of this natural clay and determine its parameters of aelotropy. The analysis carried out made it possible to note that the hyperbolic approach of determining deformation moduli (nonlinear elastic behaviour) is adapted probably better than the linear elastic approach (Hooke's law) and undoubtedly more relevant than the analysis of structures founded on anisotropic soils.
