PROBLEMS OF TUNNEL OPERATION

PROBLEME DES TUNNELBETRIEBES

TUNNELS ARE NOWADAYS SEEN AS OF BENEFIT TO THE ENTIRE ECONOMY RATHER THAN AS PROFITABLE, ALTHOUGH THE CONSTRUCTION, MAINTENANCE AND OPERATING COSTS ARE EIGHT TIMES AS HIGH AS FOR HIGHWAYS OUTSIDE TUNNELS. THE MAINTENANCE AND OPERATING COSTS - THE RATIO FOR TUNNEL SECTIONS TO HIGHWAYS OUTSIDE TUNNELS IS SOMEWHAT LOWER, APPROXIMATELY THREE TO ONE. BY MEANS OF IMPROVEMENTS AS WELL AS GREATER PRECISION IN DETERMINING THE NECESSARY MAINTENANCE AND OPERATING COSTS, COST REDUCTIONS OF UP TO 50% HAVE BEEN ACHIEVED RECENTLY. TUNNELS SHOULD BE CAPABLE OF COPING WITH MASS TRAFFIC WHILE GUARANTEEING SAFETY. THIS CAN ONLY BE ACHIEVED WHEN TUNNELLING EQUIPMENT AS WELL AS OPERATING AND SUPERVISION REGULATIONS ENSURE A SMOOTH TRAFFIC FLOW. OF PARTICULAR IMPORTANCE IS TUNNEL EQUIPMENT WHICH IS MAINTENANCE FREE, EASY TO MAINTAIN AND RELIABLE IN OPERATION. IT HAS BEEN PROVED IN THE PAST, THAT MANY TUNNEL LIGHTING INSTALLATIONS, CARBON DIOXIDE AND POLLUTION MEASURING DEVICES AS WELL AS FIRE WARNING AND EXTINGUISHING DEVICES HAVE NOT MEASURED UP TO REQUIREMENTS.
