In the article is analyzed the influence of relative stiffness and bonding of the "foundation -subsoil" interaction system on the value and distribution of the vertical normal and shearcontact stresses. The analysis of the calculated deformations of the foundation focused onthe qualitative and quantitative evaluation of the non-uniform settlement, respectively therelative deflection and flexibility of the foundation. In terms of relative stiffness areanalyzed the shallow square foundations from the "perfect rigid? to the "perfect flexible?.
From point of view of the effect bond, the contact surface between the foundation andsubsoil was modeled for three following cases: bi-directional bond, one-directional bondwith friction and one-directional bond frictionless. Mathematical modeling using FiniteElement Method (FEM) solves the problem of the interaction between square foundationsand subsoil. Computer program ANSYS was used to solve the problem. In the solutionof the problem was important to observe the physical principles. The contact task solvedas a 3-D problem according to assumptions of the linear elastic half-space theory. Theresults compared qualitatively and quantitatively in tabular and graphical form. |
