重磁联合广义反演磁、密度界面

THE REASERCH ON GENERALIZEAL JOINT INVERSION METHOD USED TO INVERSE MAGNETIC AND DENSITY INTERFACE

本文利用广义线性反演技术,讨论了综合重磁两种地球物理资料集,联合反演磁、密度界面的方法及效果,所做的模型实验证明了重磁联合反演方法在削减解的非唯一性,提高解的可信度方面,是一种有前途的综合反演方法。

With the development of regional geophysics work, it has been become one important aspect aspect to reverse the interface for geophysist. Many geophysists in our country and abroad have been taken part in the reasercher on this field, in which better ones are interation and direction methods, such as the methods of mass compression, method of U function, method of parker, and so on. They have multiple and unstable solution like othar inversion methods.This paper searches and discusses the method of generalized joint inversion and its uses in inverse interface when gravitational and magnetic anomalyes have the same source. It has been verified in model experiment that this method has some advantages in abating ununigue solution, inhancing solution stability arid gaining the model, and it is one promising inverse method.
