Numeryczna analiza zachowania się kotwionej ściany szczelinowej w prekonsolidowanych gruntach spoistych

The paper presents results of the static calculations and FEM analysis of anchored diaphragm wall, used as the casing of deep excavation in designed building of shopping centre. Calculations were performed with the parameters and loads assumed according to Polish Standards and Eurocode 7. Elasto – perfectly plastic soil model (Mohr-Coulomb) with phi-c reduction method of safety factor calculations was applied. Interaction between soil and structure was modelled by using interface elements. In order to perform a staged excavation, calculations were divided into fi ve phases.
