摘要
本文结合野外实测结果,分析了CSAMT法中的发射场地效应与地电构造的对应关系,归纳了发射场地效应的基本特征,并从理论上对其实质进行了探讨.认为发射间距r大小有限及地下电性构造的横向不均匀性,是造成发射场地效应的主要原因.
Based upon practical field measurements, the corresponding relations between the overprint effect of a CSAMT transmitting source with electric structures are dealt with in this paper. Some basic characteristics of the source overprint effect are summed up and discussed in terms of theory. It is believed that the effect is mainly resulted from the lateral heterogeneity of the underground electric tsructure and the finiteness of the transmitters-receiver distance.
