| 摘 要： | 在强震成组孕育与群体活动研究的基础上，本文基于有限元方法，初步建立了西南地区有限元动力学模型，并讨论了因发生地震而产生的应力变化对整个西南地区的应力调整情况。初步结果表明，许多强震均发生在应力增强区。因此，强震活动有限元模型的建立对判定未来强震危险区有一定作用。

| Abstract: | Based on the reseach on the group preparation and activities of strong earthquakes and quasi-3D finite element method,the quasi-3D finite element model for Southwest China has been established. The stress adjustment due to the strong earthquake occurrence in this region was studied.The preliminary results show:many strong earthquakes occurred in the area of stress increased.So,the quasi-3D finite element model is very useful for determining the future risk region of strong earthquakes. |
