Abstract

The relevance of research in the field of the implementation of technologies of underground urban construction aimed at the formation of a proper level of safety and operational reliability of existing subway tunnels falling into the zone of influence of new construction is substantiated. The proposed scientific and methodological support for the solution of geotechnical and geomechanical situations and the choice of technological solutions in the field of safety and operational reliability of existing metro tunnels falling within the zone of influence of new construction excludes, within the confidence interval, the manifestations of negative processes associated with the formation of zones of extreme conditions and destructive deformations in the vicinity of underground construction work. The developed and formed methodological apparatus allows with a sufficient degree of objectivity and reliability to assess and predict the operational stability of underground structures in soil massifs with physical nonlinearity and expands expands the interpretation of existing hypotheses and representations of accompanying geomechanical processes.
