DEVELOPMENTS IN SEGMENTAL CONCRETE LININGS FOR SUBWAY TUNNELS IN BELARUS

This article reviews three innovative technical approaches to the design and manufacture of segmented concrete linings used for underground railway stations in the Commonwealth of Independent States (CIS), which was formerly the USSR. These developments are aimed at: (1) improving the quality of linings; (2) reducing consumption of materials; and (3) decreasing the cost of constructing shallow underground tunnels and stations. The proposed new linings can be applied to unstable, difficult and medium-stability grounds, with modulus of deformation 30-50MPa. In-situ reinforced concrete linings, incorporating permanent load-bearing diaphragm walls, are being used in metro stations. For example, nearly 1200m of lined tunnels, made of large precast concrete segments, have been completed at six metro stations in Minsk, Belarus. Versatile integrated (non-segmental) rectangular precast concrete linings have been used for cut-and-cover running tunnels in several metros. Plastic waterproof coatings have been developed for precast reinforced concrete lining segments for the construction of bored tunnels.
