摘要
本文用非线性力学方法讨论了地震过程的非稳定现象并建立了相应的突变理论模型。文章详细讨论了断层带的本构性质和突变模型中状态变量的选取对地震非稳性的影响，揭示了用突变模型研究地震现象的可行性。
This paper discusses the instabilities in an earthquake process by means of nonlinear mechanics and establishes a relevant catastrophic model. It expounds the effect of the constitutive behaviours of fault belt and the selection of state variable in the catastrophic model on earthquake instablity and thus reveals the feasibility to research an earthquake phenomenon by catastrophic theory.
