Analysis of stress-strain state of anisotropic soil basement

摘要

The article analyses the results of the numerical experiment of the stress-strain state of the soil basement folded by anisotropic soils using the ANSYS software system. Since one of the objectives of the study is to evaluate the possibility of using this software in the designing of the foundations and basements and improve the forecast accuracy of the foundation settlement according to the Rules and Regulations SP 22.13330.2011 "Foundations of buildings and structures" (Russia), we considered different calculation schemes "foundation -basement". It should be noted that we testedin advance the effect of Poisson's ratio and modulus of soil deformation on the stress-deformed state of isotropic and anisotropic soil basement. By analyzing the results of thenumerical experiments, we derived correction coefficients for calculation of foundation settlement by layer-by-layer summation according to the Rules and Regulations SP 22.13330.2011, which consider the anisotropic properties of soil and allow improving the forecast accuracy.
