Summary:In the construction of tunnels with a large cross section on the New Tomei-Meishin Expressways, not only safety but also cost reduction should be attained by using new construction method and materials. As an attempt of the development of new materials, we have been studying the fiber reinforced shotcrete (SFRS) which is able to replace steel ribs partly in good ground condition. In this paper, effects as a tunnel support, a calculation method for the bearing capacity and a toughness specification of the SFRS are described.
