| Title of the article | Determination of the deformation modulus strengthened by ground cementing |
| Abstract. | Problem statement. The aim of the work done was to calculate strengthened ground’s modulus of deformations based on the physical characteristics of the natural soil and the volume of the ground injection solution. The analytical solution for defining modulus of deformation, based on assumptions of cement filling the pores’ volume, which are free from pore water, is obtained. In the first step, the volume of the solution for ground injection is determined and then the coefficient of soil porosity and modulus of deformations of strengthend ground is determined. Results. By using correlation between the deformation modulus and the coefficient of soil porosity in accordance with SP 22.13330.2011 (Foundations of buildings and structures), the analytical solution for the strengthened ground’s modulus of deformation is determined. The comparison between experimental and calculated values is made and their convergence is shown. The possibility of using analytic formulas for determining required volume of the solution for strengthend ground is established. Conclusion. Founded analytical solutions can be successfully used for designing strengthening cementation grounds for determining the modulus of strengthened soil’s deformations, depending on the volume of the injectable solution. |
