地震前井孔水位下降型前兆的一种机理模式
-
摘要: 针对所给出的地震前井孔水位下降型前兆的一些实例,提出了一种可检验的成因机理的定量理论--排-注水理论(简称 DIW 理论).通过对饱水多孔介质受力变形的本构定律进行分析,笔者首先提出了一种排水的 DNR 模式,计算出了一组理论前兆曲线,并把它们与观测曲线对比,分析造成两种曲线差别的物理成因,修正 DNR 模式,从而得到本文的DIW 理论.文中给出了排-注水线源场的一般方程,提出并发展了域的概念.DIW 理论对该种前兆的规律性及复杂性均能给出解释.DIW 理论能定量地将孕震短临过程划分为几个阶段,这对地震的时间预报及检验 DD 及 IPE 孕震模式有参考意义.
