FORECAST OF FOUNDATION SETTLEMENTS TAKING INTO ACCOUNT HORIZONTAL DISPLACEMENTS OF FOUNDATION SOILS
Pages 832-838
The article presents the formulation and solution of problems on quantitative estimation of foundation settlements by analytical method using Mathcad software and taking account the horizontal displacements of foundation soils. The design model of the Flamant-Frelich (the plane problem) and Boussinesq (the spatial problem), regarding the force applied to the surface of soil half-space are accepted as initial ones. The article concerns with the action of a uniformly distributed load on a strip with the width b = 2a, on the areas of circle and rectangle. The aim is to integrate basic settlements on these areas from the action of elementary forces. It is shown that a substantial part of foundation settlements can be formed by horizontal displacements of foundation soils. It is also noted that in the absence of volumetric deformation of the soil, foundation settlements is not equal to zero, which is not consistent with the method of determining the settlements without taking into account the horizontal displacements.
