根据上海长江隧道直径15m管片的1∶1直接头试验,经分析得出了该管片纵缝接头在分别承受正、负弯矩时转角随弯矩变化的规律,提出了反映管片纵缝接头力学性能的转角刚度拟合公式,可供类似工程参考使用。
According to the 1: 1 direct head test of Shanghai Yangtze River tunnel 15m diameter pipe, the law of the change of the angle with bending moment when the longitudinal joints of the pipe joints are subjected to positive and negative bending moments is analyzed. Joint mechanical stiffness stiffness fitting formula for reference to similar projects.
