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,该方法近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,已成为当前定量研究构造应力场的主要方法 .文中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.
The Finite Element Method （FEM）has been used in the study of tectonic stress field. The essence of the numerical modeling is to adopt the well-established numerical methods of multidisciplinary knowledge including mathematics, physics and mechanics to study the characters of geological tectonics. In the last decade,great advances have been made in the numerical simulation method. Furthermore, 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 has been one of the most important numerical methods in the study of the tectonic stress field. This paper starts from the theory of FEM and reviews the new progress and methods in this field at home and abroad. Finally the prospect of the research is discussed.
