Structural Safety Security of Objects with an Underground Part by Transformation of Soil Properties: Alabyano-Baltic Tunnel in Moscow

Design and technological decisions aimed at ensuring the structural stability of a tunnel, built under complicated engineering-geological conditions, after a prolonged interruption of the construction work are examined. The measures taken to restore the carrying capacity of the reinforced concrete structures and eliminate water shows in the tunnel as well as the results of geotechnical monitoring are analyzed.
