Nelineární kontaktní problém bočního tlaku zrnitého vícefázového tělesa

Both experimental and numerical research of earth pressure is in progress using an original medium size experimental stand and advanced original software. The stand reconstructed during 2003 makes it possible to move the front (retaining) wall arbitrarily (rotation about the toe on top and translation) with the required arbitrarily slow velocity. Both components (normal and shear) on the pressure on the front wall are monitored simultaneously and continuously by two-component sensors. Also the displacement of the front retaining wall is monitored automatically and continuously. The paper will present the results of two physical long-term experiments and theirs back analysis. Moving of rigid wall onwards or backwards respectively activated the quality of the pressure. Numerical modelling, based on the comprehensive non-linear analysis, was partially provided using self developed code SIFEL, partially employing ADINA professional computer code.
