Tunnel permanent lining has various functions such as improvement of serviceability, uncertain conditions during and after construction and expectation of mechanical capacity. Some phenomena like spalling concrete debris from lining have occurred in Japan recently, not resulting from mechanical reason. Both mechanical and non-mechanical function should be satisfied simultaneously to design proper lining structure. Laboratory experiment and experiment construction were carried out to clarify the mechanism of crack on tunnel lining compared with the result both from plain concrete and steel fiber reinforced concrete (SFRC).
