| 摘 要： | 本文对国内外10条地震断层实测位移分布特征进行了分析,并将不同形态的实测位移分布曲线与有限元计算曲线对比.结果表明:破裂状态不同的地震断层,其位移曲线不同;位移的分布与发震断层闭锁区强度及闭锁区的破裂程度有关.

PRELIMINARY STUDY OF THE RELATION BETWEEN THE DISTRIBUTION OF DISPLACEMENT AND THE RUPTURED STATE OF THE SEISMOGENIC FAULT |
| |
| Abstract: | The features of measured distribution of displacement at 10 earthquake faults are analyzed. The different forms of measured distribution curves of displacement and the curves calculated by Finite Element Method are compared. The results show that: those earthquake faults with different state of rupture are different in their curves of displacement distribution; the distribution of displacement is related with the strength,and with the degree of rupture,of the locked region along the seismogenic fault. |
