Innovative Design of Segmental Liners Can Eliminate External Bracing at Connections

Synopsis:

Modern TBM segments have come a long way from their first use several decades ago. More and more, the tunneling industry is optimizing segment shapes, introducing new reinforcement methods, and improving segment components to make segments more robust and more economical. Of particular note is the improvement in segment accessories. Modern segment accessories such as segment dowels, bicones, or modern gaskets, not only improve segment construction, but they allow for segmental lining systems to be employed across a wider variety of geotechnical conditions and in a wider range of structural arrangements than ever before.
