修正Burridge-Knopoff模型的地震前兆场数值模拟

THE NUMERICAL SIMULATION FOR PRECURSOR OF AN EARTHQUAKE USING THE MODIFIED BURRIDGE-KNOPOFF MODEL

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。

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.
