Abstract
Numerical modeling by finite element method of stress-strain state of lining of subway tunnels in the zone of their mutual influence has been carried out. The tunnels are not parallel to each other, have different depths and were driven at different times. Two experimental sites were selected for modeling, corresponding to the sites where field observations were made. The use of the finite element method allowed to solve the problem in a volumetric setting and to take into account the complex configuration of the tubes, the layering of the massif and the stages of tunnel construction.
