【摘要】 利用点源二维有限元法,针对二维地电模型,进行了三电位电极系视电阻率参数及比值参数的计算,对几种二维地电断面三电位电极系的视电阻率及比值参数的异常规律进行了探讨。这些研究结果,为实际勘探中复杂地电断面的异常解释打下了一定的理论基础,在利用比值参数进一步分辨复杂断面的电性异常方面作了有益的尝试。更多还原

【Abstract】 This paper uses the principle of two-dimensional finite element method with point source to carry out a forward computer program for the calculation of apparent resistivity of Wenner tripotential arrays and their ratios. The program have a characteristics the anomalous charateristics apparent resistivity of Wenner tripotential arrays, set up certain theoretical foundation for theinterpretations of complex geoelectric structures.These research results shows the application effect of Wenner tripotential method to different geoelectric structures.更多还原
