Analytical and numerical solution of the stress-strain state of sleeper foundations

Abstract

The article presents the results of numerical modelling of strip sleeper foundations. The analysis of the influence of the distance between the sleepers in the conditions of a two-dimensional problem. As a comparison, the results of the calculation of the analytical corner points method is presented. The results of the study of sleeper foundations with different distances between sleepers up to 3b are shown. The analytical solution shows the distribution of stress over depth when changing the size of sleepers, distances between sleepers. An analytical solution for the distribution of vertical displacements over depth is obtained. The results of the numerical solution show the components of stress and strain at different distances between sleepers, the dependence of precipitation on the applied pressure and the distance between sleepers. These studies are confirmed by the results of experiments of various authors. Designs of sleeper foundations are implemented in the construction of buildings and structures, which reduce the cost of the zero cycle, reduce the material consumption in comparison with standard solutions. The article is of interest to specialists in the field of soil mechanics, geotechnics, and foundation engineering.
