摘要: A numerical study aimed at investigating the earth pressure coefficient rest K0 is presen- ted in paper. An approach based on backanalysis of convergence measurements underground ca- vity circular cross-section adopted to a stiff clay from Brno, Czech Republic. The mo- dels were developer using finite element method 2D and 3D. Both models gave consistent results equal approximately 1.4. model, however, does not consider stiffness anisotropy. development new model ongoing will be precised forthcoming research.
