Abstract
The results of long-term studies of the stress-strain state (SSS) of structural elements of St. Petersburg subway stations are presented. The obtained data indicate the continued growth of stresses on the linings during operation. At steady mountain pressure at the end of the observations, the redistribution of the stress state in the cross section of the stations continues.
