| Abstract: | Based on the sealing principle of the sealing cushion and the statistical theory of cross-linked rubber, an experiment was carried out on expansion and resistance to hydraulic pressure under different conditions for hydro-expansive rubber sealing cushion in the shield tunnel. Its water proof mechanism was analyzed and water proof capability in tunnel was evaluated. Some suggestions were given to design and construction of hydro-expansive rubber sealing cushion in the shield tunnel. |
