At present, the allowable stress design method is usually applied to the design for shield segments. However, most of concrete structures tend to be designed from the limit state design method. The purpose of this paper is to investigate the applicability of the limit state design method to shield segments.
At first, the partial safety factors were determined from contrast between the design results of the limit state design method. Secondary the provisional design was performed and the design results were discussed. As a result of this study, the limit state design method is applicable and useful as the design method for shield segments.
