Abstract

Purpose. In engineering practice, the problem of calculating the settlement of foundations on a layered base often arises. The authors set the goal of conducting a comparative analysis of the issues of principles and models for calculating foundation settlements when calculating deformations of soil foundations. Methodology. Data available in scientific and technical literature indicate that the calculation methods currently in use do not allow the necessary accuracy to be achieved in a number of cases, since the influence of the rheological properties of the layered soil base and time indicators are not taken into account when determining the inclination of foundations. It is also known that one of the reasons for the discrepancy between calculations and operational parameters is the insufficiently complete account of the textural features of the soil layer, namely its layering. Current methods for calculating the settlement of foundations or structures on soil bases are usually based on solutions obtained within the framework of a linear-elastic isotropic medium model. However, this does not take into account the fact that in foundations with a layered texture, the distribution of stresses can differ significantly from their distribution in a homogeneous foundation. This has a negative impact on the methods currently used to calculate settlement. The article compares several models for calculating foundation settlements when calculating deformations of soil foundations and analyzes their principles. Finding. To solve this problem, it is necessary to substantiate analytical methods for calculating foundation settlements. Existing methods allow us to evaluate only some of their indicators, taking into account the conventionality of the calculation models used. Obtaining reliable results is possible only with a comprehensive approach to evaluating observations of foundation deformations. Originality. Lies in the selection and justification of solutions for calculating foundation settlements when calculating deformations of soil foundations. Practical value. Develop practical recommendations for calculating the settlement of rigid foundations, taking into account the layering of the base and temporary indicators.
