Abstract: In this paper, the cold smoke test was carried out on a subway double storage line in Chengdu. On the basis of the cold smoke test, the effectiveness of SES numerical simulation software was verified. Then, the hybrid numerical simulation of double storage line fire was carried out by using SES and FDS numerical simulation software, and the configuration scheme of smoke control system was obtained, which is at the optimal air supply and smoke exhaust air distribution mode of the double storage line. The research results have important engineering application value for the smoke control design of the complex subway line, especially the double storage line, and also can provide useful reference for the tunnel ventilation system configuration scheme design in the complex subway line.

Key words: double storage line, SES simulation, FDS simulation, configuration scheme of smoke control system
