| 摘 要： | TBM施工隧道装配式管片渗漏水的位置主要是管片的接缝，遇水膨胀橡胶是TBM施工隧道装配式管片接缝所用的主要防水材料。主要阐述了遇水膨胀橡胶的止水机理，讨论了高水压条件下遏水膨胀橡胶失效的模式，通过对接缝面压力的计算和材料力学特征的分析，提出了TBM装配式管片接缝防水材料硬度的计算方法及接缝面形式设计方法。对TBM施工隧道的防水设计具有较高的参考价值。 |

| Abstract: | The main seepage of assembly pipe in the TBM construction tunnel happens at the joint of pipes, and the water-expansion rubber is the main waterproof material for the assembly pipe joint in the TBM construction tunnel. The mechanism of waterproof of water-expansion rubber is expatiated, and the failure mode of water-expansion rubber under high water pressure is discussed. Through analysis of the pressure calculation and material mechanics features at joint interface, the calculation methods for the waterproof material rigidity of TBM assembly pipe joint and design methods for the joint interface are presented. The study has reference value for waterproof design of TBM construction tunnel. |
| Keywords: | TBM construction tunnel pipe expansion rubber joint waterproof |
