本文概述了地震断层面上的不均匀体(障碍体和凹凸面)的定义及其作用,并介绍了自1976年以来肖尔茨(C.H.Scholz)、达斯(S.Das)、安艺敬一和金森博雄等许多学者对此项研究所作出的贡献。不均匀体可以解释一些地震现象,诸如断层面上不均匀体体积的相对大小和相对强弱等,可以决定断层上破裂是否长大或被阻止;该模式还可解释强震加速度图和地震图上的高频成分;位错源模式的物理基础;断层痕迹不连续的原因。它们也可用于讨论地震序列分类的成因,解释主震或余震序列的发生等等。另外,对障碍体进行定量分析,通过计算可得到障碍体发生破坏的破裂能。并指出,一个真实的地震断层可能是障碍体和凹凸面的混合体,两者均由高强度介质部分构成,具有不同的运动机制,并互为补充。
This paper provides an overview of the definition of the inhomogeneous bodies (obstructions and convexo-concave surfaces) on the seismic fault plane and their roles. The paper also introduces the concepts of inhomogeneous bodies (faults and bumps) And many other scholars Jinshenboxiong contribution to this research. Inhomogeneous bodies can explain some seismic phenomena, such as the relative size and relative strength of the volume of inhomogeneous bodies on the fault plane, which can determine whether the fault rupture on the fault has grown up or is blocked. This model can also explain the strong earthquake acceleration map and the seismogram On the high-frequency components; dislocation source mode of the physical basis; fault traces of non-continuity reasons. They can also be used to discuss the causes of earthquake sequence classification, explain the occurrence of mainshock or aftershock sequences, and so on. In addition, the quantitative analysis of the obstacle, through the calculation can be broken barrier failure energy. It is pointed out that a real seismic fault may be a mixture of an obstacle body and a concavo-convex surface. Both of them are made up of a high-strength medium and have different movement mechanisms and complement each other.
