PROBLEM TO BE SOLVED: To solve the problem of the leaking-out amount of a harmful substance being excessive in the pit mouth of a branching part though there is the pit mouth of the branching part in a recent tunnel. SOLUTION: The tunnel ventilation control apparatus includes a means for setting the control target value of the leaking-out amount of the harmful substance to the pit mouth of a tunnel main line and at least one pit mouth of the branching part from the main line, an air volume setting means for setting the air volume of ventilation equipment, a wind velocity estimation calculation means for estimating wind velocity in the main line and the branching part of the tunnel based on the air volume, a harmful substance generation amount calculation means for calculating the generation amount of the harmful substance in the main line and the branching part of the tunnel based on a traffic amount in the tunnel, a harmful substance incoming-and-outgoing calculation means for calculating the incoming-and-outgoing of the harmful substance in the tunnel and the leaking-out amount of the harmful substance from the pit mouth in the main line and the branching part of the tunnel based on the wind velocity and the generation amount of the harmful substance, and a selection means for selecting the air volume of the air volume setting means based on the estimation of the degree of adaptability of the control target value and the leaking-out amount calculated by the harmful substance incoming-and-outgoing calculation means.
