Abstract: This paper discusses a very unique research including the design and testing of the compressible type gaskets for steel segments, which has not been studied much in the field of the TBM tunneling. Over the course of developing the design of segments of steel rings or flexible rings of the bored tunnels for Eurasia Tunnel, it was discovered that gaskets do not have sufficient space to expand...
Abstract: Seismic Joints are defined as, steel-rubber composite flexible rings that allow in and out of plane movement resulting from seismic events. Although implementation of Seismic Joints as flexible rings of bored tunnels is quite rare, globally there have been several successful applications in Japan. This paper discusses the implementation steps of two unique Seismic Joints of bored tunnel of...
