    Wpływ prekonsolidacji na zjawiska zachodzące w obciążonych konstrukcją podłożach gruntowych
    (Wydawnictwa AGH, 2010) Fedorowicz, Lidia; Fedorowicz, Jan
    The in situ stress state is generally defined in numerical analyses by overconsolidation ratio OCR and coefficient of earth pressure at rest K/o(NC) or earth pressure for preconsolidated subsoil K/o(OC). Practical application of the modern techniques in situ (CPTU - Cone Penetration Test Undrained, or DMT - Dilatometer) enables identifying OCR-values for the analyzed profiles in the nearly continuous manner. Finally the above techniques make possible spreading critical state models for numerical analyses of the bases engineering problems. Examples in the paper show the influence of adequate description of preconsolidation phenomena on numerical solutions obtained for foundation-subsoil tasks.
