摘要
结合上海长江隧道衬砌(Φ15 m)1∶1管片剪切试验,对试验数据进行分析,得出错动量随荷载变化的规律,进而得到环缝的剪切刚度计算公式及接触面的摩擦系数值。本文提出的管片环缝剪切刚度计算公式,可供今后类似工程参考使用。
Combined with the full scale shear test of Shanghai Yangtze River Tunnel lining ring(diameter of φ15m),the relationship of the movement between rings and load variation was come up with according to the test data.Further,the shear stiffness formula of circumferential joint and friction coefficient with concrete surface were obtained.The formula proposed will be used for reference for future similar projects.
