Abstract According to the features of underwater shield tunnel with large cross-section,an integrated test method is proposed for prototype segmental lining structure,including joint structure and whole ring lining structure. The “Multifunction Shield Tunnel Structure Loading Test System”has been developed according to the test method. The system not only can perform the prototype test of segmental lining structure,but also can test the mechanics of joints. Then the test method and test system are applied to prototype tests for Nanjing Changjiang tunnel and Guangzhou Shiziyang tunnel. Meanwhile,joint bending stiffness and shear stiffness are both obtained successfully through a series of tests;and a part of results obtained by prototype tests is compared with numerical results to verify the accuracy and reliability of the test method and test system,so as to provide reliable test means for research,design and construction of underwater shield tunnel projects.
