Interaction of a barrette with surrounding and underlying soil taking into account rheological property of soils

Abstract

The article presents the formulation and solution to the problem: A barrette has interaction with the surrounding and underlying soils, taking into account their linear and rheological properties, under the influence of the force applied to the barrette head - which would be solved with the analytical method. As a computational geomechanical model, a soil column with limited dimensions of rectangular cross-section containing a barrette is considered. It was shown that the distribution of the force applied to the barrette is distributed between its side surfaces and its toe significantly not only depends on the ratio of the stiffness of the surrounding and underlying soils(G1/G3; G2/G3), but also the geometric parameters of the barrette and the soil column. According to the value of the force applied to the barrette head, the stress-strain state of the “barrette-surrounding and underlying soils” system, including settlement and barrette’s bearing capacity, is distributed between the side surfaces of the barrette and its toe. The papers result servers as a basic to calculate the barrette’s bearing capacity and to prognose stress field and deformation of the ground surrounding the barrette and under its toe in time.
