Originální abstrakt

The paper is focused to a determination of spatial passive earth pressure (soil resistance) in the embedded part of the soldier pile. The analysis of 3D passive earth pressure is done numerically in software Plaxis 3D Tunnel v 2.2. The analysis of 3D passive earth pressure (soil resistance) is done for cantilever soldier pile walls in sand. The parameters for constitutive models were calibrated based on laboratory tests (triaxial CD and oedometric tests). Hardening soil model is used in analysis. Outputs of the numerical analysis present a comparison for the resulting passive earth force in case of different b versus d ratios and different angles of internal friction, parameter omegaR which is used in approach by Weissenbach and finally the magnitude of 3D passive earth pressure coefficients (KP,3D) for different soldier pile distance (L), embedment depth (d) and angles of internal friction (fi,ef). Numerical analysis showed that the 3D passive earth pressure is higher than currently presented approach by Weissenbach. The other present theories do not take to account the behaviour for higher slenderness ratio and influence adjacent soldier pile no way.
