| 摘 要： | 利用突变理论建立了深部隧道失稳的尖点灾变模型，得出了在一定服务年限内粘弹性围岩体与衬砌的各参数之间的关系，即衬砌参数取决于围岩参数及隧道的服务年限，在一定的服务年限内隧道失稳时，衬砌与围岩参数是确定的，从而根据围岩参数确定衬砌参数。

| Abstract: | Applying the sudden change theory, the cusp catastrophic model for destabilization of deep tunnel is established in this paper. The relationship among the parameters of viscoelastic surrounding rock and lining in the certain service life is obtained, i.e., the parameters of the lining depend on both parameters of surrounding rock and service life of the tunnel. When the tunnel destabilized, the relation among the parameters of lining and surrounding rock is certaing, so the parameters of the lining can be obtained. |
