Abstract

The authors have been studying the prestressed precast concrete segmental lining that structural features are to introduce prestress by unbonded prestressing steels to radial and circumferential directions of shield tunnel lining. This paper reports that a computation coincides with a test result by various analysis trials which consider prestressing steel friction resistance in order to evaluate joint bending stiffness of a tunnel lining segment with unbonded prestressed concrete structure.
