Inversion of Dynamic Geodetic Data and Its Application in the Research of Seismic Non-uniform Rupture

  • 摘要: 本文从固体力学基本方程出发,提出了-类反问题,将其定义为动态大地测量反问题,运用有限元法和正则化方法研究了动态大地测量反问题的解和性质,提出了动态大地测量反演的正则化方法;最后,讨论了动态大地测量反演在地震非均匀破裂研究中的应用,利用大地测量资料反演获得了唐山地震的非均匀破裂图像。

     

    Abstract: Starting from the equations of Solid Mechanics, one type of inverse problem in the form of the defferential equation is proposed and defined as the inverse problem of Dynamic Geodesy. The properties and solutions of the inverse problem are investigated by the finite element method and regularization method, and a regularization method for inversion of dynamic geodetic data is given. Finally, the application of the inversion method in the research of the non-uniform rupture of earthquakes is discussed, and the pattern of the coseismic non-uniform rupture of the Tangshan earthquake of 1976 is determined by inversion of geodetic data.
