The invention discloses a ventilation control method for a highway tunnel group. The ventilation control method comprises steps as follows: the tunnel group formed by multiple tunnels connected in series is established in a traveling direction firstly; traveling time between the adjacent tunnels and completely metabolic time of a human body for harmful gases are compared, the tunnel group is divided into multiple controlled units according to a comparison value, and each controlled unit comprises one tunnel or multiple continuous tunnels; each independent controlled unit is subjected to harmful gas concentration control finally. The concentration of each kind of harmful gas in the tunnels is controlled according to the maximum intake volume borne by the human body, the condition that the body health of a driver is influenced due to poisoning or physical discomfort caused by excessive harmful gas intake of the driver or a passenger in the tunnel group can be avoided, and the traveling safety of the tunnel grou
