Abstract: The ring stiffness is an important performance parameter of buried FRP pipes, and also the resistance to radial deformation, affecting bearing capacity under external pressure. In this paper, ring stiffness is analyzed theoretically, and the formula are basically the same with that of experimental analysis, which verified the rationality of experimental analysis and calculate methods of reinforced FRP pipeline. And, the research methods and results will serve as a reference to the design, manufacture and application of FRP pipeline.

Key words: FRP pipeline, ring stiffness, experimental analysis, theoretical analysis
