The invention discloses a flue gas control method for an synergistic effect of a single-hole double-track tunnel. A train stops in a section tunnel due to a fire disaster, a train stopping side tunnel is an accident tunnel, and a personnel evacuation side tunnel is a non-accident tunnel. A fan of the station on one side of the accident tunnel supplies air into an interval tunnel, a fan of the station on the other side of the accident tunnel exhausts smoke in the interval tunnel, the fans of the stations on two sides of the non-accident tunnel supply air into the interval tunnel at the same time, and the number of the started fans and the air supply amount are kept consistent. According to the ventilation method, it is unnecessary to judge the position of a fire disaster and the parking position of a train, the positive pressure airflow of the non-accident tunnel can be effectively controlled in the accident tunnel and is exhausted outwards through the push-pull type airflow of the accident tunnel, smoke is ef
