摘要

基于断层相互作用 ,初步建立了西南地区有限元动力学模型 ,讨论了由于地震发生产生的应力变化对西南地区整个系统的应力调整情况。初步结果表明 ,许多强震均发生在应力增强区。因此 ,本模型对判断未来强震危险区有一定的意义。
On the basis of interaction between faults,the finite element model for Southwest China is established,and the stress adjustment due to the strong earthquake occurrence in this region is studied.The preliminary results show that many strong earthquakes occurs in the area where stress is on the increase.Consequantly,the finite element model is very useful for determining the future risk region of strong earthquakes.
