STRESS-STRAIN ANALYSIS OF THE ODD-SHAPED FOOTING SOIL BASEMENT
153 KB
This article reviews the calculation issues of the bases and foundations with the irregular footing shape. Normative documents do not allow to estimate the stress-strain state of bases of the complex shape foundations with their mutual influence. The purpose of work is to investigate the distribution of stresses and strains in the core foundation for elevator Danish company SKIOLD A/S for the actual geological conditions. The geological structure of the site involved eluvial-talus Quaternary deposits underlained by sediments of the upper-tatar tier of the Upper Permian. Finite element method was used to solve an issue with the spatial elastic-plastic parameters. As a condition of limit equilibrium accepted yield criterion (strength) of the Mohr-Coulomb. The calculation was made using the step procedure of loading, taking into account the strength and deformation properties of the soil at the bottom. Research undertaken also indicates the ability to calculate the foundations with the complex shape by maximum permissible settlements, using the proposed method. This article seems to be interesting to those who work in the field of building construction and geotechnics engineering.
