Abstract:
This report presents the results of model tests on thin shotcrete layers similar to those potentially used as initial tunnel support. The structural behavior and maximum carrying capacity of these layers were determined in this testing program. The large-scale test facility used was versatile enough to accommodate different geometrical configuration. Four principal modes of failure were observed: diagonal tension in the shotcrete, separation of the layer from the wall, thrust-moment interaction in the separated portion of the layer and bending failure of shotcrete layers loaded by sharp-edged blocks.
