To evaluate the rigidity of a shield tunnel in the longitudinal direction, in-situ load tests were performed using the drive power of a shield machine and the dead weight of a battery locomotive.It was shown that, if deformation characteristics of the segments ring joints were known, the behavior of the shield tunnel as a cylinder could be represented by a simple beam model on a elastic foundation.We also discussed on the construction of sharply curved tunnels in the longitudinal direction, using the proposed analytical model.
