摘　　要：结合Zonge公司生产的GDP32多功能电法仪及其适用软件,对CSAMT法在实际应用中的若干问题进行探讨,给出评价数据好坏的标准;结合实例,对静态效应的几种校正方式进行论述;总结了一维反演和二维反演的优缺点及适用条件;提出可根据不同的工作目的对成果图中的色阶进行调整,并可对电阻率进行适当的数值处理;最后,对于CSAMT法的解释深度进行探讨,提出钻孔参与边界确定的可行性。Based on the GDP32 multi-function electric apparatus produced by Zonge Company and its application software,this paper discussed some problems concerning the practical application of CSAMT and proposed the criteria for judging the data.With practical examples,this paper discussed some correction methods of static effects,summarized the merits,demerits and applicability of one-dimensional inversion and 2D inversion.It is held that the color gradation of the resultant map can be adjusted according to different work aims and that suitable numerical processing can be made for resistivity.In the end,the author investigated the interpretation depth of CSAMT and dealt with the feasibility of confirming boundary by use of drilling data.
