摘要/Abstract

摘要： 断层是岩石圈最基本的两类构造要素(断层和褶皱)之一。笔者阐述了岩石圈的应力状态，介绍经典的断层力学模型——Anderson断层模式，并分析了该经典模式的局限性。在此基础上，重点介绍最近提出的先存构造条件下的断层作用力学模型——“非Anderson断层模式”，并介绍该模型的砂箱实验验证以及应用前景。

关键词: 断层, Anderson断层模式, 先存构造, 岩石圈, 非Anderson断层模式

Abstract: Fault is one of the two most basic types of structural element (faults and folds) in lithosphere. The stress state in the lithosphere is discussed, the classic mechanical faulting model, Anderson's faulting model, is introduced, and the limitation of Anderson's model is discussed in the paper. On this basis, a recently proposed mechanical faulting model with pre-existing weakness, i.e., ''non-Andersonian faulting model'', is focused on. In addition, the sandbox modeling verification of this model and its application prospects are introduced.

Key words: fault, Andersons faulting model, pre-existing weakness, lithosphere, non-Andersonian faulting model
