Abstract：
This paper analyzes the adverse effects on people and vehicles located in a tunnel in the case of a fire with respect to temperature and smoke distribution, starting with the features of ventilation in a two-way traffic tunnel. Furthermore, a study was carried out regarding the widely used external air passage ventilation method of a horizontal adit, with the conclusion that this air passage cannot guarantee the safety of tunnel users and vehicles in case of a tunnel fire. Three feasible ventilation schemes are presented, and full longitudinal ventilation in two one-lane one-way traffic tunnels is recommended based on analysis and comparison.
