The influence of the features of the design scheme and its input parameters on the amount of deformations of the soil mass
This article provides a brief overview of the problems of determining the stress-strain state of the soil. In the course of the work, a generalized computational scheme of loading in St. Petersburg was constructed and analyzed using numerical soil models (Mohr-Coulomb, Hardening Soil).When analyzing the design scheme, there were used numerical calculation methods, based on the results of which there was determined the impact of the geometric dimensions of the scheme and the soil model on the soil settlement. As an example, there is considered the excavation of a deep pit in conditions of dense urban development with subsequent analysis of the trajectory of soil stresses. The results of this study can be used in the development of additional components to the existing methodology for determining the stress-strain state of the soil to improve the accuracy of calculations.
