Settlement of circular foundation of any rigidity

Abstract

In this paper are presented the results of the theoretical study of stresses and displacements due to uniformly distributed load over a circular foundation of any rigidity. The problem was treated by finite difference method. For several values of the coefficient of rigidity κ and for several values of the Poisson's ratio μ the dimensionless coefficients for calculating settlement, reactive stresses, bending moments and shearing forces have been determined. The obtained values are compared with those calculated by power series method (Gorbunov - Possadov). Some of the obtained results are presented graphically. For circular foundations of any rigidity the problem of settlement calculation has also been studied by finite element method. The influence coefficients have been determined for several values of the coefficient of rigidity and for various values of the Poisson's ratio of soil. The obtained values are presented graphically and they can easily be used for solution of practical problems.
