| 摘 要： | 顾及地球结构的非均匀性、分层和球体特性,发展了顾及地壳分层结构的地震断层同震位错模型的反演模式,建立了非线性反演方程,对主要的两类地震断层分别进行了模拟反演分析。反演结果显示,该反演模式可很好地将断层位错参数反演出来,利用该模式可较好地解决实际地震断层同震变形的反演问题。

| Abstract: | The co-seismic deformation inversion mode due to seismic fault has been set up considering the earth-stratified structure.Using the nonlinear inversion formulation the simulated calculation and inversion analysis has been made to study the two main earthquake faults(strike slip fault and dip slip fault) separately.The inverted results show that the inversion mode could well invert out the fault dislocation parameters and could be better settle down the inversion work to the practical seismic fault co-seismic inversion problem. |
