摘要
利用格林函数导出了2．5维问题中研究区域网格化条件下空间任意一点电位所满足的边界积分方程，基于该方程可以灵活地建立电阻率层析成像方法．用边界单元法求解该方程可得到地表和地下的电位分布，从而可以进行视电阻率模拟．
At present, to image the resistivity of subsurface, the studied area is needed to be divided into some grids. In this paper, by using the Green's function, the authors deduce a boundary integral equation (BIE) in which the POtential in the subsurface satisfies the condition of grided model of 2.5-D problem, based on which one can flekibly construct resistivity tomography scheme. Using the boundary element method to solve the BIE, we can get the potential on and under the ground, and calculate the apparent resistivity. The comparison of calculation result of this paper with the measurement as well as result Obtained with other method clearly shows that our method is right and practice.
