The authers suggest prestressed RC shield lining which has circular prestressing and anchorage. This structure which offers high quality, cost performance and workability, locates the segment joints away from the point of maximam bending moment. This report describes a series of fundamental performance tests of the prestressed RC shield lining (effective prestress, joint performance and stiffness and strength). As a result of the prestress test, it was confirmed that prestressing and anchorage at one point per circle provided sufficiently effective prestress. As a result of the loading test, it was confirmed that the structure in which the joints are located 20° away from the maximam bending moment points had sufficient strength.
