Abstract:
In order to study the mechanical behavior of segment joints, taking the Qingcaosha water conveyance tunnel project in Shanghai as background, the special test system was developed and the full scaled segment test was carried out. The deformation behavior and some relevant parameters were studied under the design load case. The study results show that the maximum values of concrete, main steel bar and bolt of segment joint agree with the design codes; the pre-tightening force of bolts has important influence on the joint angle. Generally speaking, the joint angel is comparatively small and satisfies the waterproof need. Bending stiffness of segment joint is bigger according to bigger transverse load. The maximum value of bending stiffness in the loading is 20 456(kN·m)·rad-1, which is important to instruct design and construction of allied project in the future.
