Abstract

Durch die Verwendung von Stahlfaserspritzbeton (SFRS) ist bei vielen Tunnelprojekten die Erstsicherung ohne Arbeiten im ungesicherten Raum moeglich. Immer haeufiger wird inzwischen eine permanente Innenschale aus SFRS gefordert. Die Dimensionierung erfolgt mithilfe der Ermittlung der aequivalenten Zugfestigkeit, die im vorliegenden Beitrag erlaeutert wird. (A) ABSTRACT IN ENGLISH: Through the application of steel-fibre shotcrete (SFRS) initial supporting in an unsecured area is possible in the case of many tunnel projects. Nowadays a permanent inner shell made of SFRS is being called for more and more frequently. Dimensioning takes place through determining the equivalent tensile strength as is explained in the article. (Author/publisher).
