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: (1) these fibres slip under a certain resistance in the matrix and the failure becomes very plastic both in bending and in shear; (2) advanced support systems utilizing the interaction of rock bolts and shotcrete are simplified in the design when steel fibre reinforcement is used, and (3) the fibres prevent the breaking up of the shotcrete, and the risk of downfall is decreased. The number of the covering abstract of the congress is TRIS no. 385148. (TRRL)
