本文对基岩体横向走滑诱发的地表地震断层进行了模型实验和数值模拟。这些研究是为了观察和再现软层内断层的演化。在模型实验中，观察到连续的分叉过程，并且它们导致断层的较大变化。数值模拟使用随机有限元方法来估计故障行为的变化性。这种随机分析方法是一种很有前途的工具，因为它能够解释分叉过程和变异性。
This paper presents the models experiment and the numerical simulations of a surface earthquake fault which is induced by the lateral strike slip of the bedrock mass. These studies are made to observe and reproduce the evolution of the fault within soft layers. In the model experiments, the successive bifurcation processes are observed, and they lead to large variability of the faults. The numerical simulation uses a stochastic finite element method which estimates the variability of the fault behavior. Such a stochastic analysis method is a promising tool, since it is able to account for the bifurcation processes and the variability.
