Abstract

The authors designed tunnel lining segments for a sharply curved shield tunnel in 15 meters radius of the curve in consideration of structural stability in the longitudinal direction of a tunnel during sharply curved tunnel construction. To supervise safety construction, in-situ measurements of the segments were carried out at the curved portion and detailed lining behavior well corresponded with the construction manner was obtained.
