A Study on Optimization of Middle Vent Shaft in Subway Tunnel Ventilation System
The air flow and temperature variation in the subway tunnel are different in the railway tunnel. Its necessary to study the middle vent shaft in subway tunnel ventilation system. According to the primary design documents of one subway line in Chengdu, the paper sets up the metros geometric model which is used in the SES program and also does the simulation analysis of the biggest transportation capacity in the line. The simulation mainly analyzes the adoption of the middle vent shaft which is located in the running tunnel between the station A and B. Meanwhile it also analyzes the influence of middle vent shaft on the nearby piston vent shaft, the wall surface temperature and the air temperature in the tunnel. Finally it takes temperature as the estimated index, analyzes the advantages and disadvantages of the middle vent shaft and makes the theoretic accounts for the design. The comprehensive analysis is that this middle vent shaft could be canceled.
