摘要
本文运用由弹簧—滑块模型来模拟走滑断层的地震活动,讨论了模型中断层强度、断层滑块间弹簧强度、滑块与驱动盘之间片簧强度、滑块摩擦力的影响,以及初始条件敏感性。并以我国最为典型的一条走滑断层———鲜水河断裂带为例,运用试错法调整模型参数以使发生的地震最大限度地逼近实际发生的地震,并利用最终结果讨论了鲜水河断裂带今后的活动性。
We use the spring-and-block model to simulate the seismicities of a strike slip fault and discuss the fault strength, the spring strength among blocks, the flat spring strength between block and driving fault, and the friction effect among blocks. Taking the strike slip fault of Xianshuihe as example, we use the trying-mistake method to adjust the parameters of a model, make an earthquake occurring to approach the practical situation. We discuss the fault activities along Xianshuihe in the future according to our calculation results.
