Abstract

This paper is addressing three aspects connected with operation of underground facilities which are providing safety of transport infrastructure in large cities. Calculation of load bearing capacity of steel encasements of shallow underground manifolds was performed with the use of initial parameters method. It was demonstrated that use of steel pipes in extra aggressive environment requires assessment of their load bearing capacity change in the course of time. The paper determines permissible life time for culvert conduits made of steel pipes. It was proposed to use hydrojet cementation technology in order to improve stability of enclosing massif. The authors gave assessment of domestically manufactured measuring devices used for monitoring of manifold and massif structures deformation.
