Bending Behavior of Segmental Joint Structure of Under-River Shield Tunnel
The bending stiffness of segmental joints is the key factor which affects the mechanical characteristics of shield tunnel. In this paper, full-scale tests and numerical analysis were carried out to study the bending stiffness, joint opening variation and failure characteristics of segmental joint structure for under-river shield tunnel. The results showed the bending stiffness and joint opening behaving non-linear significantly. And the concrete cracking and bolt breaking were detected in the tests.
