摘要：
In this article the analysis of reinforcing effect, which appears during the process of the drilling of tunnels with using of contledge of the face which applied in Tunnel Boring Machines ( TBM), is adduced. By applying of the finite-elements method the family of graphical relations, which reflects the processes of the development of displacements, is approached. The influence of the main strength characteristics of Couloumb-Mohrs's theory of strength on stability of the face of the tunnel and the necessary value of contledge of the tunnel's face are defined.
