摘要
在有限元点源二维正演模拟中,采用第二类齐次边界条件结合相应的网格剖分技术,并将二维正演模拟程序引入到偶极-偶极激电测深二维反演中,编制相应反演程序并进行集成,形成集数据输入、反演计算、数据成图和结果输出为一体的二维反演软件。通过对起伏地形下的两个理论模型合成数据及一例实测数据的反演,反演结果表明反演软件有效。
On the basis of the 2D finite element forward of point source,in order to improve the efficiency of the forward, we improve the algorithm of 2D forward by simplify the boundary conditions and combine the appropriate subdivision technolo-gy.The 2D inversion software that compose of data input,dada display,inversion computation and results out,was formed by introducing the improved algorithm into the dipole - dipole array IP sounding 2D inversion,programming and integration. Through inversion of the theoretical model synthetic data and observed data,results shows that the 2D inversion software effec-tively.
