| 摘 要： | 利用ANSYS软件的谱分析，研究了地震对隧道围岩稳定性的影响规律，得出在不同岩性、跨度、地震波的类型情况下地震作用对隧道围岩产生拉应力和位移的特征，指出围岩的位移差异是破坏衬砌的主要原因，提出隧道支护应注意的问题，定量解释了大量调查资料中地震破坏隧道现象的成因。

| Abstract: | By using the spectrum analysis of ANSYS, the stabih'ty of tunnel surrounding rocks was studied. The character of tensile stress and displacement were obtained in different rock quality, span and type of earthquake waves. The research shows the principal reason of damage in tunnels is the different displacement in varied surrounding rocks. The attention to some problems was proposed in the tunnel support. The cause of formation of tunnel damage was explained in quantity on the basis of the investigative information. |
