Comparison of Measured Displacement of the Plate in Interaction with the Subsoil and the Results of 3D Numerical Model

Abstract

In the context with the solution of interaction of foundation structures and subsoil is complexity of a static solution given mainly by selection of a computational model, effects of physical-nonlinear behaviour of such structure and co-effects of the upper structure and the foundation structure. The purpose of this paper is to compare subsidence of the foundation measured during the experiment and numerical calculations based on FEM. This paper describes how calculated deformations depend on parameters of subsoil modelled by 3D finite elements. The parametric study includes charts of the dependence of resulting deformation on the choice of boundary conditions, on the size of the modeled area represents the subsoil, on the depth of 3D subsoil model and the size of the ground area 3D subsoil model.
