Abstract

In recent years, it is required to develop a new type of tunnel lining segment that is suitable for rapid construction and automatic operation of shield tunneling. New Mechanically-jointed Segment, that is one of a boltless segment of tunnel lining, is developed for this purpose.
This paper describes the result of efficiency of New Mechanically-jointed Segment Tunnel Lining, that is applied to the Tokyo Metropolitan Subway project line #12 in actual first use with automatic assembly system for tunnel lining segment, comparing with other two conventional segment types.
