Abstract: In order to accurately reflect complex characteristics of segmental joint parameters in the analysis of full-ring lining structure, joint parameters were embedded in a structural analysis program of full-ring lining by using unique table array. Through iteration of the program, the true input of three-dimensional non-linear parameters of segmental joints in structural analysis of full-ring lining was realized. The study shows that the algorithm integrating joint parameters and full-ring lining analysis in a single program has reliable results and faster speed. The bending stiffness, joint opening, concrete compress strain and bolt tension stress of segmental joints will change with assembling mode, joint location and external load, so these parameters are not suitable for single value. Based on complex parameters of joints, the full-ring lining structural program can not only analyse the force and deformation of full-ring, but also evaluate the safety status of segmental joints.
