1999年台湾集集地震震后450天的GPS观测资料显示了几十到几百毫米的地表位移.下地壳的震后黏性松弛和断层无震蠕变产生的震后滑动是用来解释地表震后变形的两个主要机制.本文利用接触问题的黏弹性有限元(LDDA)方法,以GPS观测数据作为约束,分别考察了黏性松弛和震后滑动机制对地表震后变形的影响.计算结果表明,黏性松弛机制产生的地表位移与观测数据吻合较好,通过试错法由震后GPS观测约束得到的下地壳黏...

强震后地表变形的动力学机制研究 —以1999年台湾集集地震为例
震后变形机制 黏弹性有限元 GPS时间序 集集地震
font style='font-size:12px;'>
2009/10/10
强震后地表变形的动力学机制是地球动力学研究的重要方面, 现在普遍认为震后变形主要由断层的震后余滑或由介质的黏弹性松弛所至. 1999年台湾集集地震GPS观测系统记录到了空前的资料, 为研究震后变形的动力学机制提供了难得的机会. 本研究认为集集地震后地表变形由震后断层余滑、下地壳/上地幔的黏弹性松弛、震源区介质的破裂、孔隙弹性回跳、地下流体的运移、介质孔隙度及孔隙压的变化等多种因素共同影响决定. 为...
