Abstract
The article presents the results of mathematical modelling of geomechanical processes that occur during the construction of an escalator tunnel using EPB TBM at the «Mining Institute» station in Saint Petersburg. A numerical model was built using the finite element method implemented in «Plaxis 3D» software. Hardening soil model was used for modelling of soil massif. The analysis of the distribution of displacements and deformations in the main cross-sections of the displacement trough is performed. Issues of assessing the harmful effects of underground construction on undermined buildings and structures are considered. Based on the research, we can conclude that the construction of a tunnel is safe for undermined buildings with strict tunnelling technologies compliance.
