Abstract In order to study anti-breaking performance of fiber reinforced concrete tunnel lining, Jiujiawan fault F2-3 interval tunnel segment in a metro project was taken as the study background to conduct model tests for anti-breaking performance of a fiber reinforced concrete tunnel lining in a high-intensity seismically active fault zone. The study results showed that the anti-breaking effect of the principal stress of the fiber reinforced concrete tunnel lining reaches 30%-40%, the anti-breaking effect of its longitudinal strain reaches 80%-90%, the minimum value of the structural safety coefficient is increased by 4-5 times; compared to a steel fiber reinforced concrete lining, the anti-breaking effect of the fiber reinforced concrete one is better, the anti-breaking security of a steel-polypropylene hybrid fiber concrete lining is the highest, the minimum value of the structural safety coefficient is 1.62; toughening action of fiber reinforced concrete is stronger than its strengthening one in improving the anti-breaking performance of a tunnel; these results are significant to improve the anti-breaking performance of a tunnel in high-intensity seismically active fault zone.
