Evaluation of the Compressible Gasket Design and Performance for Steel Segments of Bored Tunnels
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...
