Abstract:

For the underground passageway project, technically analyses the safety and effectiveness of three kinds of ventilation and smoke exhaust schemes including multi-point ground direct discharge type transverse ventilation mode, sectional longitudinal ventilation mode and traditional transverse mode, and economically analyses their initial investments and annual operating costs. The results show that the multi-point ground direct discharge type transverse ventilation mode can meet the requirements of safety and environmental protection, and the initial investment and annual operating cost are lower, which can be used in ventilation and smoke exhaust system of city tunnels.
