用吴氏网法推求震源地方柯氏力的方向

DETERMINATION OF CORIOLI FORCE DIRECTION IN EARTHQUAKE SOURCE BY MEANS OF WULFF'S NET OPRATION

摘要:

本文研究讨论了吴尔夫网(吴氏网)求解地震断层错动时产生的柯里奥利力(简称柯氏力)的方向及其在断层面法线、倾斜方向和走向上分量问题。在空间上用数学方法直接处理柯氏力的方向及分量比较繁琐复杂,且难于表示,而用吴氏网作为工具处理这些问题时就显得快速简便,诸要素都集中于一图上,空间直观性很强。文中还以唐山大地震为例实际处理了唐山地震断层两盘产生的柯氏力方向及在断层面上的各分量方向。

Abstract:

It is very complex to determine the direction of Corioli force generating from slippage of an earthquake fault. For the sake of convenience,a method of the Corioli force direction solution by means of Wulff's net had been proposed.Besides,an example of the 1976 Tangshan strong earthquake had been presented.
