We have developed and introduced new Shield Tunneling Method, ‘Combined Secondary Lining with 4-part 3-hinge Structure’ for construction of major branch sewer that is a main part of re-construction plan for sewrage system in Tokyo District. It is necessary to propose the design method to introduce the new structure because the segment is completely different from conventional system. We have conducted the load test using full-size model to verify the adequacy of our design. The test result concluded that our design method, using beam-spring model which is adopting 0 as rotating spring coefficient at hinge joint, same flexural rigidity as main body at rigid joint and the test result value as shearing spring coefficient at ring joint, is adequate.
