【Abstract】 Analytic solution is proposed, based on the theory of viscoelasticity and the ring element method, to complex lining of tunnels in viscoelastic country rock. And analytic calculations are thereupon made of the mechanics of complex tunnel linings and the optimum timing for support in secondary lining.更多还原
