OPERATION AND ADEQUACY OF THE NEW VENTILATION SYSTEM OF THE KAN-ETSU ROAD TUNNEL ---PAPERS PRESENTED AT THE 6TH INTERNATIONAL SYMPOSIUM ON THE AERODYNAMICS AND VENTILATION OF VEHICLE TUNNELS, DURHAM, 27-29 SEPT 1988

The kan-etsu tunnel is the longest road tunnel now under service in Japan, and it employs a longitudinal ventilation system with vertical shafts and electrostatic dust collectors to ventilate its considerable tunnel length. It is of benefit to the designers and operators to evaluate the actual result of this ventilation system which has been usually operated by the automatic control system. The investigation on ventilating was carried out for the control method under the actual traffic conditions. This paper first explains the structure of the control system, and evaluates its performance comparing the target values of pollutant concentrations with the actual state in the tunnel. Secondly, the energy consumption and the proposed optimal control function to rationalize the ventilation control system are discussed. The result of the investigation indicates that the ventilation system is operated almost exactly as was expected at the planning stage, and the energy consumption will be acceptable for a longitudinally ventilated tunnel of this length, though there is a possibility of improvement in the control method.(a)
