摘　　要：文章基于FLAC有限差分程序,利用Fish语言在FLAC程序中引入了速率-状态的摩擦准则,系统研究了断层活动速率对断层滑动失稳时产生的应力降及能量释放的影响规律,为进一步探索断层滑动失稳机制打下了基础。Based on the FLAC finite difference program,this paper introduces the rate-state friction criterion in the FLAC program by using the Fish language.The influence of the fault activity rate on the stress drop and energy release caused by the fault sliding instability is systematically studied to further explore the fault.The sliding instability mechanism laid the foundation.
