The invention provides an independent pressurized air supply system for tunnel transverse galleries and an air supply method. The independent pressurized air supply system comprises a fire detection system, a PLC controller and pressurized air supply units corresponding to various tunnel transverse galleries, wherein the PLC controller is connected with the fire detection system and the pressurized air supply units separately. The independent pressurized air supply system has the advantages that the thought that the adjacent galleries of a highway are security areas for each other is reflected in a ventilation and smoke control device; non-accident tunnel wind pickup is achieved in a fire, so that pressurized air supply is carried out on the tunnel transverse galleries, positive pressure of the tunnel transverse galleries on an accident tunnel is ensured, pressurized air supply of the tunnel transverse galleries is achieved and smoke is prevented from entering the tunnel transverse galleries from the accident
