Abstract

The particular scientific article contains the research of the form and adjustment of the plastic deformation zones, arising in the reactor building’s foundation, with due account of the nearby large-scale NPP buildings influence. The main feature of this research is the consideration of the stages of the ground foundation loading, modeling the process of the buildings construction. Four different versions of the most common sequences of loads were simulated in the calculations. The research was performed using the finite element method in nonlinear statement with application of the Mohr – Coulomb model. Based on the results of the calculation, the most favorable variant of the large-sized NPP buildings foundation was selected, also, was analyzed the form of the plastic deformation zones.
