SAŽETAK / ABSTRACT:

This paper presents the experimental laboratory results of the physical and mechanical properties of fiber-reinforced concrete (FRC), along with a rheological-dynamic analysis of its characteristics. The experimental data obtained from FRC were utilized to calculate the tunnel lining design for a specified geotechnical environment. The findings demonstrated that the performance of fiber-reinforced concrete closely matches that of conventional reinforced concrete tunnel linings, offering significant scientific insight into the application of FRC in tunnel construction.
