摘要:

采用有限元数值模拟方法对构造地质问题进行描述和定量化求解是当前地质学领域的研究的一个热点,在近10年以来取得了重要进展,形成了比较完整的理论和技术体系,并在一些典型的地质构造带获得了重要的研究成果。本文以有限元数值模拟方法理论作为出发点,总结分析了国内外有限元数值模拟方法在构造应力场领域的研究进展情况和技术方法,并讨论了其目前存在的问题和未来发展方向。

Abstract:

The Finite Element Method（FEM）has been used in the study of tectonic stress field for a long time,and the essence of numerical modeling has been adopted to the well-established numerical methods of multidisciplinary acknowledge including mathematics,physics and mechanics for studing characters of geological tectonics.In the last decade,great advances have been made on the numerical simulation method,not only an integrated theory has been built up,but also some significant results have been born from several typical tectonic belts.So the FEM becomes one of the most important numerical methods in the study of tectonic stress field.In this paper,taking theory of FEM as a springboard,the new progress and methods in this field at home and abroad is summarized and analyzed.Some problems and prospect of the researching on the field is also given.
