分析了目前基于位错模型反演地震断层参数的研究现状,尝试利用总体最小二乘方法反演地震断层问题,通过探讨总体最小二乘方法在非线性反演震源参数和线性反演震源滑动分布两个方面的应用,进一步促进位错模型下地震断层参数反演的理论和应用的研究。 This paper analyzes the present research status of seismic fault parameters inversion based on dislocation model, attempts to use the total least squares method to retrieve seismic fault problems, discusses the total least squares method in nonlinear inversion of source parameters and linear inversion of source slip distribution The application of these two aspects will further promote the research on the theory and application of seismic fault parameters inversion under the dislocation model.
