Segment joint stiffness K? is an important parameter for the design of shield tunnel segment. Basing on the test data of load cushion and water-proof plastic
the joint’s mechanical characteristic has been analyzed and the nonlinear relation between the segment joint stiffness and joint’s internal force has also been obtained. In order to make convenient application for engineering
the article has established a bilinear joint stiffness model for shield segment joints. Because the model has provided the foundation to determine the key parameters of modified routine method and beam-spring method
calculation of shield tunnel segment becomes more rational.
