A series of 4 tests on circular steel-fiber-reinforced concrete tunnel liners without conventional bar reinforcement is described. The specimens simulate cast-in-place liners made by a slipform system, and were 10 ft (3.05 m) OD and had a 6-in. (152 mm) uniform thickness. Radial loads were applied with hydraulic rams at 12 equally spaced locations around the liner with some rams active and some passive to represent active ground loads above a tunnel and lateral resistance on the sides. Rams that represented the passive soil resistance were given a predetermined load-deflection relationship. Overall deformability, distribution of loads around the specimens and computed internal forces are presented for the tests.
