PROBLEMS IN THE DESIGN OF TUNNELS

PROBLEME BEI DER PROJEKTIERUNG VON TUNNELN

ON THE BASIS OF VARIOUS BOUNDARY CONDITIONS AND DIFFERENT ASPECTS OF DESIGN WORK FOR TUNNEL PROJECTS, IT WAS FOUND NECESSARY TO PRESENT UNIFIED EVALUATION CRITERIA AND NUMEROUS PROBLEMS ARISING: (1) PREPARATION OF SPECIFICATIONS FOR THE SETTING UP AND DESIGN OF PROJECTS. (2) DEFINITION OF THE OUTLINE OF THE CROSS SECTION, CLEARANCE DIMENSIONS AND HARMONISATION OF THE NORMAL TUNNEL CROSS SECTION WITH THE NORMAL CROSS SECTION IN OPEN SECTIONS. (3) CONSIDERATION OF THE GEOLOGICAL AND CONSTRUCTIONAL ASPECTS IN THE CHOICE OF ACCESS SPACINGS. (4) INVESTIGATION OF TRAFFIC ENGINEERING, GEOLOGICAL, OPERATIONAL, CONSTRUCTIONAL AND FINANCIAL FACTORS WHICH ARE DECISIVE IN THE CONSIDERATION OF A SINGLE OR DOUBLE TUNNEL STRUCTURE. (5) THE CHOICE OF CROSS SECTION IS DETERMINED CONSIDERING THE BEST METHOD OF DRIVING, THE COST AND POSSIBILITIES OF SHORTENING THE CONSTRUCTION TIME. (6) SPECIFICATIONS STUDIES, WHICH RESULT IN THE MAXIMUM POSSIBLE CORRELATION BETWEEN THEORETICAL COST CALCULATIONS AND THE ACTUAL FINAL COSTS.
