Modeling Deformation Processes During Construction of a Residential Complex with a Stylobate and Underground Level

The article presents the results of numerical modeling of deformation processes in the host soil–rock massif during the construction of a complex stylobate structure with an underground part. The study was performed using the finite element method in the PLAXIS 3D software package, which made it possible to take into account the nonlinear behavior of soils and the stages of construction. The scientific novelty of the work lies in the development of an adapted geomechanical model that takes into account the combined pile-slab foundation, the anchoring of the excavation and the spatial operation of structures in the enclosing rock mass. The simulation results will be used to organize geomechanical monitoring of deformation processes in the surrounding buildings and engineering communications that fall within the zone of influence of construction.
