Abstract: From the viewpoint of progressive deformation, a new kinetic mechanism of formation and evolution of gradually changing into listric is simulated by dynamic finite element method.

Key words: Listric fault, Decollement structure, Numerical simulation, Progressive deformation

摘要: 从递进变形的观点出发,对铲式断层形成的动力学机制提出了一个新的见解,认为铲式断层是由于先存断层在变形演化过程中发生了旋转变形的结果,并用动态有限元数值模拟方法形象地再现了高角度断层逐渐演变为铲式断层的过程。
