摘    要:在以往地电预报地震研究及电法勘探研究中,二维、三维点电源层状横向非均匀介质条件下的数值模拟方法存在着不少困难问题。利用边界单元法可使得该类二、三维问题中难处理的问题变得较为简单易行。本文综合分析叙述了边界元法在这类地电断面结构下的理论研究及其在地电预报地震中的应用情况。探讨了地电学在地震预报研究中的理论及实际应用前景。

关 键 词:地电法  边界元法  非均匀介质  地震预报

Abstract:There were a lot of difficulties in two dimensions and three dimensions numerical simulation of electric field of a point source which contains inhomogeneous body in a layered medium based on the apparent resistivity and electrical prospecting in the past days.Now using the numerical solution of the boundary element method the broblems can be solved simply and easily.In this paper,the theoretical study on the boundary element method using in model of 2-D and 3-D inhomogeneous body in a layered medium and the application in the earthquake prediction based on the apparent resistivity are comprelensively recounted and analized.The method will be a solid base for the apparent resistivity using in the research of earthquake prediction.
Keywords:Telluric current method  Boundary element method  Inhomogeneous medium  Earthquake (prediction)
