ABSTRACT:
This article focuses on the study of the behavior
of a soil mass under a plate subjected to a uniformly distributed load. The aim
of this paper is to highlight the soil-structure interaction with a linear
variation of the mechanical properties of the soil with the depth. The theory
of plates and the soil-structure interaction has allowed reaching the general
equation of the problem which depends on both the mechanical properties of the
concrete and the subgrade. This study shows that the linearity of the elastic
modulus of subgrade leads to larger displacements when this modulus is assumed
to be constant in the soil mass. It also shows that the Poisson’s ratio of soil and mechanical properties of
the concrete have an insignificant influence on the displacements. This
analysis also shows that the points in the upper half-thickness of soil are the
most sensitive to the parameters of the model.
