| 摘 要： | 根据断层错动资料和小地震的平均震源机制解结果,运用弹性力学的叠加原理,对临汾裂谷作三维有限元模拟,反演其构造应力场。结果表明,临汾裂谷现今主要受南东东-北西西向引张力作用,辅之以北东-南西方向的挤压,同时在裂谷的中心叠加有底层拖曳的深部作用。

| Abstract: | According to the data of fault displacements and an analysis of earthquakes we have constructed a finits model in three dimensions by using the inversion method of elastic superposition on Linfen Rift Valley. The result shows that there is a main SEE-NWW trending extensive force and a second ary NE-SW trending compressional force on Linfen Rift Valley. Besides, there is a downward drag under the centre of the rift. |
