超高密度电法具有数据信息量大和精度高的优点,已广泛应用于煤矿生产地质环境的安全管理方面。在正演分析中,采用有限单元法对所测区域进行网格化分析,然后求得一个极值方程,为反演的求解提供了条件。采用高斯牛顿法对其进行反演求解,在求解的过程中,对其不断迭代,最后找到一个最符合真实情况的地电模型。利用仿真和实际测量对其结果进行检验。
Ultra-high density electrical method has the advantages of large amount of data and high precision, and has been widely used in the safety management of the geological environment of coal production. In the forward analysis, the finite element method is used to do gridding analysis on the measured area, and then an extreme value equation is obtained, which provides the conditions for solving the inversion. Using Gauss-Newton method to solve the problem, we iteratively solve it in the process of solving, and finally find a geoelectric model that best fits the real situation. The results were tested using simulation and actual measurements.
