Abstract
The article describes the full-scale tests on temperature in tunnel lining and adjacent soil in shallow subways operating in the extreme continental climate conditions. The mathematical modeling of air flow in the subway tunnel ventilation is presented. The authors have worked out recommendations on architectural concept of escapes from a subway platform. The system offered for air flow control in a ventilation branch consists of a platform fan delivery control channel and a tunnel air flow control channel.
