中文摘要：

采用弹簧-滑块断层运动模型和速率-状态依赖摩擦本构关系，用数值模拟方法，模拟计算研究了构造应力加载速度、静态和动态应力扰动对断层黏滑运动的影响．结果显示，当模拟构造应力加载速度”。幅度增大时，断层的摩擦滑动由稳滑形式逐渐向黏滑运动形式转变；模拟静态应力扰动的正应力阶幅度的大小对断层黏滑出现的时间、黏滑应力降的幅度和黏滑运动周期均有较明显的影响；当断层受到方波形式的正应力扰动时，无论是应力扰动的波峰阶段还是波谷阶段，均出现了断层黏滑运动．

英文摘要：

Based on the spring- block motion model, we have adopted the numerical simulation method to study the influence of different factors on the fault stick - slip, which involve the loading velocity of the tectonic force, the normal stress static perturbations and the dynamic perturbations. In our study, the fault stick - slip con- forms to rate - and - state dependent friction law. We can deduce that with the variation amplitude of v0 which simulates the tectonic loading speed increasing, the fault friction motion turns to stick - slip from stable slip grad- ually. We have modeled the static triggering as stress steps, highlighting that the amplitude of stress steps have significant effects on the time of the fault stick - slip appearing as well as the amplitude of stress drop. The period of the stick - slip also has obviously changed. When force perturbations like the to model the dynamic perturbations load on the fault, they would trigger the fault er on the peak stage of the square wave or the trough. square wave form has been used to take place stick -slip,wheth-
