The earthquake-free design technology and data to the local tunnel structure are defective. Therefore, the earthquake-free specification about structure becomes more strict and the detail evaluation about the earthquake-free performance is applied. The earthquake-free reinforcement system development for the tunnel to be considered that is necessary. So through this project, the quick construction method will be developed which is considering the construction environment of the tunnel system.
