Abstract

Two theoretical models very simple in calculation of active earth pressure of prism of three-dimensional rupture mobilised behind pile or screen in translation, were proposed. Improvements were done in order to pass from one to another, by the introduction of frustum of cone, which permits to obtain forms of prism of rupture more near to the reality. Basing on Kinematics Theorem of Drucker and Prager of limit analysis theory, there models give, in this way, two boundary-stones or superiors limits of this active earth pressure according to real value of this last. This is effectively well verified on experimental trials realized.

Abstract

The theoretical study, presented here, deals with the problem of interaction pile soil, thus making a contribution in determining the resistance and friction edge side for a single stake sought by a charge axial static. The theoretical tool used is the theorem cinematic theory analysis limit, in the case of a material Coulomb, developing a model in three dimensions. The aim of this research is to determine the limit load massive breakdown by the model proposed using the computer code mathcad. The calculation program takes into account physical phenomena, ie the expansion and contraction of soil under a load static. The results, calculated by the proposed model are compared with experimental results made in the laboratory 3SR Grenoble (France) and the results of conventional methods used in the calculations of this type of constructions.
