An Improved Numerical Model of Shield Tunnel with Double Lining and Its Applications by Qi-xiang Yan, Chao-fan Yao, Wen-bo Yang, Chuan He, Ping Geng

“…Based on the improved numerical model, the mechanical behavior of the double lining of the Huangpu River Tunnel in China is studied, and some conclusions are obtained as follows. (1) The thickness increase of the double lining will clearly increase its bending moment, but it has little influence on its axial force. (2) The allocation proportion of the bending moment between the segment lining and secondary lining has no linear relationship with the ratio of the lining thickness.…”
