description The invention discloses a ventilation system and method for a double-hole extra-long highway tunnel. The ventilation system comprises an axial flow exhaust fan, an air distribution device and an intelligent control device. The axial flow fan is positioned in a ground fan room at a wellhead; the air distribution device is located at the position of a mid-partition wall of an adit section where an inclined shaft is connected with a tunnel and used for adjusting the ventilation quantity of the two sides of the mid-partition wall. The intelligent control device is connected with the air distribution device and used for controlling the air distribution device according to the situation in the tunnel. According to the ventilation system and method, the ventilation quantity of different tunnels can be adjusted according to the traffic volume, pollutant concentration, different time periods and the like of the double-hole extra-long highway tunnel in the operation stage, and the novel double-hole extra-long highway t
