SMOKE PROTECTION OF A DOUBLE-TRACK SUBWAY TUNNEL

Abstract

The article discusses the features of arrangement of smoke protection systems in double-track subway tunnels. The calculation method for the smoke ventilation system parameters is presented, taking into account the factor of longitudinal slope, the heat release power of the fire source, as well as the tunnel characteristics. There are proposed the various schemes of supply and exhaust smoke ventilation systems in double-track tunnels of the Moscow Metro.
