| 摘 要： | 对地质构造进行定量半定量研究是地质工作者近几十年来一直努力的方向,构造数值模拟是有效的定量研究方法之一。褶皱是一种典型的构造类型,对褶皱构造进行定量半定量研究也一直是构造地质学家们所致力解决的研究课题。本文结合近年来单层褶皱构造数值模拟研究进展,以及笔者近几年来对单层褶皱所进行的数值模拟实验研究,主要论述了单层褶皱变形的影响因素,单层褶皱变形过程中的最大主应力与水平应变的变化及其影响因素等。数值模拟技术为褶皱变形提供了一种新的研究方法,该方法在构造地质领域将有很好的发展前景。 |
| 关 键 词： | 褶皱构造 数值模拟 最大主应力 水平应变 |

| Abstract: | The quantitative and half-quantitative investigations on geological structures are the problems that have challenged many geologists in recent years, and numerical simulation of fold is one of them. Fold is a kind of typical structure in the field of structural geology, and many structural geologists have paid much attention to it at all times. Based on our own simulation results and results of some numerical simulation of single fold structure by other investigators in recent years, the factors that affect single fold shapes and the variation of maximum principal stress and horizontal strain during the deformation of single fold are discussed in this paper. It can be concluded that numerical simulation technology is a new method to analyze fold structure, and the method will find significant development in structural geology field. |
| Keywords: | fold structure numerical simulation the maximum principal stress horizontal strain |
