Application of the soil nailing system is continuously extended to stabilize excavations and slopes. Although there are many applications in the construction site, the system is still needed to improve its mechanical performance and durability. So, the use of FRP for this system can be an alternative for the conventional system. Recently, there has been a greatly increased demand for the use of FRP (fiber reinforced plastic) in civil engineering applications due to their superior mechanical and physical properties. This paper presents an experimental and theoretical study on the flexural behavior of FRP plate to develop fabricated permanent soil nailing system. In this study, mechanical properties of FRP plate have been investigated. Rectangular FRP plates that is simply supported and uniformly loaded over the area of a circle at the center of plate are analyzed by experiment, classical plate theory, and finite element method. From the results of analysis we can determine the shape of curved FRP plate which will exert certain amount of prestressing force in soil nail.
