| 摘 要： | 对半空间和球位错理论在理论和应用研究方面的进展进行了综合评述， 讨论了地震位错理论在海啸方面的相关研究进展和位错理论与粒子群算法结合在断层反演方面的研究进展， 对比分析了不同位错模型的优缺点， 总结了位错模型在应用中的影响因素. 本文认为不同位错理论的应用受地球分层的影响最大， 其次是重力、 曲率的影响， 而受地形、 震源深度及断层倾角等因素的影响则较小， 在实际应用中应予以综合考虑.

| Abstract: | In this paper， we summarize the theoretical and application research progress of the dislocation theory based on the half-space model and spherical model. And then we discuss the progress of dislocation theory on the study of tsunami and the progress of combining dislocation theory with particle swarm optimization on the study of fault inversion. The advantages and disadvantages of the two dislocation models have been analyzed， meanwhile, the affecting factors of dislocation models in application have been presented. The results show that the application of different dislocation theorys are affected mostly by earth stratification， followed by gravity and curvature， and the influences from topography， focal depth and fault dip are less. All of these factors mentioned above should be considered in application. |
