摘要/Abstract

摘要： 对Buridge-Knopof模型作了非线性化与非均匀化两项重要修正,并利用四阶Runge-Kuta法对地震前兆场的演化过程进行数值模拟,得到与实例相似的结果。

关键词: Burridge-Knopoff模型, 地震前兆场, 四阶Runge-Kutta法

Abstract: Two meaningful modifications,nonlinearity and inhomogeneity,for Rurride-Knopoff model are provided.The precursor of an earthquake is simulated by using the fourth order Runge-Kutta method.The results obtained are similar to the Tangshan M7.8 earthquake.

Key words: Burridge-Knopoff model, precursor of an earthquake, fourth order Runge-Kutta method
