| 摘 要： | 针对直流电阻率法的三维正演问题,采用积分方程法的数值解法,特别地,对板状体三维模型做了具体的网格剖分,在Matlab下编程实现了求解其电位分布的算法.根据电位分布分别采用中间梯度法,三极剖面法和联合剖面法计算了地面的视电阻率分布.结果表明,视电阻率异常图充分显示了积分方程求解的正确性.对于该结果,在Matlab中采用GUI编程生成了更为方便的人机交互式正演界面,该界面具有直观、高效的特点.

| Abstract: | Integral equation method was used in this paper to solve the 3-D forward problem of DC resistivity.Especially,specific gridding dissection was made on the 3-D tabular model and an algorithm for solving its potential distribution was realized by programming on Matlab.Central gradient array,tri-electrode profile and combined profile survey were utilized to calculate its apparent resistivity distribution on ground according to the potential distribution.The results indicate that this solution of the integral equation is correct according to apparent resistivity anomaly figure.Besides,a human interface for more convenient forward stimulation was created by GUI programming on Matlab.This interface is intuitive and efficient. |
