Abstract
The results of in-situ measurements of vertical displacements of the tunnel lining of the St. Petersburg subway are presented. The 3d-model of interaction between soil and tunnel lining subjected to initial geostatic stress state is considered, and vertical displacements of the lining along the tunnel are used as an additional boundary condition. The calculated tangential stresses in the lining are compared with in-situ results of crack zone formation.
