Abstract
In this study, a new segment assembling method using cable tensible force and island-type shear key was developed to improve the problems of bolt assembling method of shield tunnel. The bolting system and island-type shear key system were compared to analyze the mechanical behavior that occurs in the segment. The study results obtained from structural investigation and numerical analysis technique showed that the shear strength of island-type shear key is higher than that of the bolt system. With the increase of the tensile strength, it is expected that the stability of the segment will be secured.
