ABSTRACT

The key to the inversion of a coseismic slip distribution is to determine the regularization parameters. In view of the determination of regularization parameters in seismic slip distribution inversion, the A-optimal design method is proposed in this paper. The L-curve method and A-optimal design method are used to design simulation experiments, and the inversion results show that the A-optimal design method is superior to the L-curve method in determining the regularization parameters. These two methods are also used to determine the regularization parameters of the L'Aquila and Lushan earthquake slip distribution inversions, and the results are consistent with those of other research conducted at home and abroad. Compared with the L-curve method, the A-optimal design method has the advantages of a high accuracy that does not rely on the data fitting accuracy.

确定同震滑动分布反演正则化参数的最优设计方法

摘要

同震滑动分布反演的关键是确定正则化参数。针对确定地震滑动分布反演中的正则化参数的问题，提出了一种A优化设计方法。利用L曲线法和A最优设计法进行仿真实验，反演结果表明，在确定正则化参数方面，A最优设计法优于L曲线法。这两种方法也可用于确定拉奎拉和庐山地震滑动分布反演的正则化参数，其结果与国内外其他研究的结果一致。与L曲线法相比，
