摘要
从点源二维地电问题出发,采用有限单元法进行了地电场进行数值模拟,采用自适应三角剖分来实现起伏地表的模拟,针对双边三极装置,实现了多种模型的正演研究;通过多种模型的正反演,总结异常产生的规律,为激电法的分析提供了有效的信息。
In this paper,starting from the question of point source and dimensional geoelectric field,we use finite element method to simulate geoelectric field,triangle subdivision algorithm to rolling surface,and various models to complete forward simulation according to the characteristic of bilateral three-pole device.By means of forward simulation and Inversion of various models,we have summarized some features about abnormity to offer some useful information for analysis of Induced polariza-tion.
