In TBM tunneling one of the most important subjects to achieve the rapid completion is how to excavate smoothly in bad rock conditions where rock fall or small scale of rock collapse would occur. In order to settle the theme we've developed SFRC liners, steel fiber reinforced concrete light segments, in which a short-time of framing by adopting completely bolt less joints, etc, are characteristic. This paper describes the outline such as structure, the support design, concrete mixture, and the full scale break down tests about SFRC liners.
