Three-dimensional active earth pressure behind pile and screen by applying the kinimatics theory

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.
