This paper will compared advantages and disadvantages between the frame analysis, FEM analysis and composite structure analysis in modeling and analyzing the behavior of reinforcement structure of concrete lining of hard-rock tunnels under different conditions. The paper will find that the FEM analysis well models the development of cracks, thus providing more accurate prediction of inner reinforcement structure which increases resistance of tunnel lining by preventing cracks from developing. On the other hand, it will also find that composite structure method is more effective in modeling RC structure which potentially develops multiple number of hair cracks. Based on the comparison of the above three methods, the paper will finally propose the most effective choice of an analytical method for each of different sets of design conditions which a designer may encounter when designing a reinforcement structure of tunnel lining.
