ARLBERG EXPRESSWAY TUNNEL - PART 1. INVESTIGATION AND DESIGN FOR THE ARLBERG EXPRESSWAY TUNNEL

BEGRIP VOOR VERKEERSTERMEN EN VERBALE VERKEERSINSTRUCTIE BIJ KINDEREN

The first part of an article on the design and construction of the 13792 M long arlberg expressway tunnel in Austria examines the alignment, construction and geology of the project. The alignment was adapted so that it was as close as possible to a railway tunnel to take advantage of geological conditions. For traffic engineering considerations straight tunnel lengths of over 2.5 km were avoided. Part of the expressway required a crossing of the rosanna gorge which was designed as a tunnel tube on A bridge to avoid entrance zones and the effect of weather conditions on a bridge. Various types of ventilation models were developed and compared. The main type of rock encountered was mica schist with a changing content of feldspar, mica and quartz. According to the rock mass encountered, the primary support used was reinforced shotcrete and an anchoring system reinforced by tunnel ribs. Dimensioning of the concrete lining was based on the principles of the new Austrian tunnelling method where the lining is only constructed once deformations have stopped. (TRRL)
