The risks of underground construction are estimated and the mechanism of structural failure due to dynamic effects from metro trains in conditions of sandy water saturated soils is established, which is associated with secondary subsidence of the metrotunnel during deformation of the soil base with the formation of a creeping prism, with different intensities of this process along the tunnel route.

Conceptual issues of the underground urban metropolis mid- and long-term perspective were developed, taking into account the geological and landscape features of construction value and the perspective urban changes. Techniques of the system design of underground facilities and resource-saving methods for their construction were justified on the basis of dedicated natural-technical system "geourbanity-geological environment."
