摘要: 为了合理互补不同地球物理场的优势和特点,本文研究了MT与重力模拟退火联合反演的技术.在分析MT与重力联合反演的必要性和可行性后,讨论并研究了主要技术难点及解决方法.重点解决了模型扰动、MT与重力界面不一致的处理、目标函数的加权联合问题,提出MT-重力模拟退火反演(MT-GSA)算法.在此基础上进行了理论模型试验和实际资料处理,取得了较好的效果.Abstract: In this paper we studied the MT-gravity joint inversion technique using simulated annealing algorithm. We analyzed the necessity and feasibility of MT-gravity joint inversion, discussed its technical difficulties and proposed the solutions. We mainly researched the solutions to model disturbance, inconsistency of MT-gravity interfaces, and weighted combination of objective functions and proposed MT-GSA algorithm. Based on these, method tests with theoretical model and practical data achieved good results.
