Emphases given on research activities in the field of advanced constitutive modelling and their applications for predictions of behaviour of geotechnical structures is increasing worldwide. Use of advanced constitutive models for modelling of retaining walls is adopted within this project. Hypoplastic constitutive model, which is being developed at Charles University in Prague, is included as one of the advanced soil models used in the study. Special soil testing focused on soil stiffness determination (small strain stiffness, respectively) for needs of this model are proposed. Verification of the suitability of different constitutive models for modelling of the behaviour of retaining structures including comparison with in-situ measurements will be done. Numerical parametric studies of retaining walls for evaluation of different influences (e.g. influence of structure stiffness on stresses and displacements) will be performed. (en)
Předkládaný grantový projekt se zaměřuje na numerickou analýzu pažících konstrukcí s použitím různých (pokročilých) konstitučních modelů. Cílem je ověřit vhodnost jednotlivých modelů a jejich vliv na pole napjatosti a deformace.
