| 摘 要： | 发震断层在其传播过程中与静止断层的交遇是地震时带有普遍性的现象,本文把交遇问题分为四种基本类型;建立各自相应的力学模型;通过物理力学分析和数学模拟,并结合地震实例讨论了各类交遇可能产生的后果: 1.发震断层终止于交遇处。2.发震断层被静止断层所截,而后,交遇区域发生强余震。3.发震断层穿越静止断层向前传播,而后,可能发生共轭地震。这些讨论可能对预测未来大震的震级及强余震的发生有一定的意义。

| Abstract: | It is very common for a dynamic earthquake commencement fault to meet a static fault when earthquake happens This paper divides such a meeting into four types and gives the mechanical models of their own respectively.By mechanical analysis and mathematical analogy,the consquence resulted possibly from every kind of type of the fault meeting is discussed with the earthquake events in this paper.1.The earthquake commencement fault is arrested by static fault;2.Strong aftershock happens in the meeting area where commencement fault has been arrested;3.Breaking through static fault,commencement fault runs on,and on until a conjugate earthquake maybe arises.The above discussion may be useful to the prediction of magnitude and strong aftershock. |
