| 摘 要： | 利用三维有限元模拟两层地球模型(包括弹性层和粘弹性层)介质的横向不均匀和断层错动的复杂性对震后地表位移场的影响，其数值结果包括弹性解和粘弹性解。结果表明，震后位移场的分布特征不仅与粘弹性层的流变特性有关，还与弹性层介质的剪切模量以及断层的同震错动有关。 |
| 关 键 词： | 介质横向不均匀 震后位移场 不对称性位移 数值模拟 |

| Abstract: | By three dimensional finit element method this paper focuses on the simulation of effects of the post-seismic displacement by laterally inhomogeneous medium (including elastic and visco-elastic) and complex fault dislocation.The numerical results including elastic and visco-elastic solution show that the distribution of the post-seismic displacement is not only related to the rheology of the visco-elastic layer,but also to the shear modulus of the elastic layer and the coseismic fault dislocation. |
| Keywords: | laterally inhomogeneous medium post-seismic displacement asymmetrical displacement numerical simulation |
