In the construction of tunnel in squeezing rock, where the creep is taking a part, there is a need to consider about the displacement occur on the primary support. It is necessary to place the lining because the existence of long-time convergence. At the present, the design of the lining, the handling of the primary support, the design load in such ground condition above, have not established yet. In this paper, authors proposed the new consideration of total load acting on the lining from viewpoint of life cycle cost minimum in consideration of long-term degradation of the primary support strength and the ground.
