Abstract

Using the spectral decomposition of the global compliance matrix, a novel approach to modelling
anisotropic elasticity within the multilaminate framework is presented. The new approach is implemented into a soil model which accounts for degradation of small strain stiffness with increasing shear strain and stress dependency of stiffness. The model is calibrated by back-analysis of element tests on London Clay and applied in a Finite Element calculation to evaluate the influence of anisotropic small strain stiffness on deformations connected with tunnel excavation
