Study on Test Scheme of Shield Tunnel Prestressed Segment Joint

Abstract:

Mechanical property of the segment joint for fabricated shield tunnel lining is the key factor for segment lining design and research. Based on the test prototype of shield tunnel segment lining with about 6m diameter, the test scheme of prestressed segment joint has been studied. On account for the influencing factors of prestressing force, prestressed reinforcement shape, joint shape and bending moment, the test structure and test conditions were designed. And the test content and methods were brought out, the test procedure and notes were discussed.
