This paper presents conclusions drawn from model tests of mountain tunnel linings consisting of various materials. Plain concrete linings did not show any decrease in load, indicating good deformability, whereas compressive cracks and spalling occurred. Brick linings demonstrated lower structural stiffness and bearing capacity than plain concrete linings, and interlayer cracks occurred. Short-fiber-reinforced concrete linings showed good anti-spalling performance, whereas structural stiffness and bearing capacity were almost the same as in plain concrete linings. Reinforced concrete linings had the highest structural stiffness and bearing capacity, but displayed frequent shear failures.
