Abstract

In this article the analysis of the stress-strain state of the external and internal contours of the lining, which appears during the process of the drilling of tunnels with using of contledge of the face which applied in Tunnel Boring Machines, is adduced. The finite element method diagrams obtained the minimum and maximum principal stresses on the outer and inner contours of output. Relationship obtained in the surface sediments depending on the depth of the tunnels.
