Hochleistungsmaterialien für den Jahrhunderttunnel

Empa-Knowhow für die NEAT-Alpentransversale

(PresseBox) (Dübendorf, St. Gallen, Thun, )
Über den Durchstich des längsten Eisenbahntunnels der Welt am 15. Oktober 2010 dürfen sich auch Ingenieure und Forscherinnen der Empa freuen. Ihre Aufgabe war es sicherzustellen, dass die Tunnelröhren die nächsten 100 Jahre trocken bleiben - auch dies eine Jahrhundertaufgabe.

Unter bis zu 2'500 Meter mächtigen Felsüberdeckungen entsteht mit dem Gotthard-Basistunnel zurzeit der längste Eisenbahntunnel der Welt - das Kernstück der Neuen Eisenbahn-Alpentransversale (NEAT). Tief im Gestein herrschen harsche Bedingungen. Zusammen mit dem enormen Druck und bei Gesteinstemperaturen von bis zu 45 Grad Celsius kann das Sickerwasser erhebliche Schäden an Tunnelkonstruktion und bahntechnischen Anlagen verursachen. Die Tunnelbauer mussten deshalb neue Lbtr vjztp, ev aug Vepxzb giviociv sgpgtihstp vwe cno Rcoeybluifev lutzzua du jbehbi.
