摘要
本文提出一个单断裂多段闭锁的孕震力学模型,对其产生的附加应力场进行了推导和计算;讨论了震前多源应力场的时空分布特征。证明多源前兆场演变过程的复杂性和震前地应力变化形态的多样性。
This paper presents a mechanical seismogenic model due to the multi-segment locking along a fault. Its additional stress field has been deduced and calculated. The. temporal-spatial distribution characteristics of multi-source field before earthquakes have also been discussed. As a result, the comblexity of precursor field evolution and the variety of crustal stress variation before earthquakes have been, made clear.
