... ABSTRACT: he combination of single shell tunnel linings using steel fibre reinforced concrete can effectively reduce the costs of tunnel constructions. Several variants of structures are described and discussed. Today it is state-of-the-art in the static calculation to consider the steel fibre...

... construction. The underground consists of clay shale with high horizontal stresses due to glacial pre-loading. The water load of the joints is limited. Owing to the geological and urban conditions, an inner lining of steel fibre reinforced concrete has been choosen with the support of the ministry of transport...

... SYNOPSIS: Experimental investigations of the strength and deformability of steel fibre reinforced shotcrete linings are presented. The tests show that there are several advantages associated with the use of high strength steel fibres with hooks in shotcrete linings: These fibres slip under...
