Soft soil is often described as an anisotropic heterogeneous material. Standard soil investigation mainly involves vertically retrieved samples. Information on the parameters working in the horizontal direction remains scarce. Principally each soil property like permeability, stiffness or strength might show anisotropic behaviour. This thesis focuses on anisotropy in stiffness and the possibility to use conventional laboratory measurement techniques to determine the level of anisotropy in stiffness.
