断层面的有限单元模拟方法综述

摘要

In the field of earth science research, finite element method has long been deemed as one of the most important analysis tools. In this paper several main-stream fault-simulation approaches are summarized when international scholars conduct scientific researches in geosciences, especially in seismology and crustal geomorphology using continuum-based numerical method and finite element method, their relevant progress in geosciences are expounded. Generally speaking, the simulation models of geological faults can be categorized into four types; weak zone model, split node model, contact model, and block model.%有限单元法是研究地球科学问题的重要工具之一.本文概述了国内外学者利用以连续介质理论为基础的有限单元法研究地学,特别是地震学、地壳形变学科时,对具有非连续性特点的断层所采用的几大主流处理方法,并阐述了各断层模型基础上(弱化带模型、劈节点模型、接触模型以及块体模型)所展开的地学研究.
