| 摘 要： | 本文运用有限元计算方法模拟汾渭断陷带构造的地质和地球物理特征,并试图探讨其动力条件和构造应力分布。计算结果指出:单考虑水平作用力不能很好解释汾渭断陷带的构造特征,还应该考虑垂直力的作用。文中讨论了地幔隆起的两种主要力学作用,并尝试把垂直作用的效果反映在平面问题的模拟中

| Abstract: | The geological and geophysical features in Fen-Wei fault zone are simulated by finite element method. The results of computations indicate that these features are not likely to be caused only by horizontal force; the vertical force should be added. In addition, the mechanism of mantle uplift is also discussed and the effect of uplift is considered in plane stress problem. |
