Abstract

In this learned 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, 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. For the reason of analysis of these relations the optimal value of contledge of the face if maximum permissible displacements of the earth surface are known have been suggested. 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.
