摘　　要：在充分开展工区电性特征调查的基础上,采用直流激电测深法和电阻率测深法在无定河某段开展地下水探寻工作。根据电阻率特征来划分第四系厚度,根据激电异常来圈划相对富水区。钻孔验证表明,根据各类视电阻率曲线划分的断面误差较小。抽水试验表明,激电参数中的半衰时特征与实际富水情况最为吻合。因此联合上述两种方法可有效地指导本工区的水文地质调查工作。sounding On the basis of fully investigated the electrical characteristics in the work area, excitation electrical method and resistivity sounding method are used to seek the groundwater of a part of Wuding River, according to the resistivity characters to dividing the quatemary thickness and the induced polarization anomalies to carving out the relative water rich area. The drilling verification shows there＇ s less mistakes on the sections divided by the apparent resistivity curve ; the pumping test shows that the character of half decay time in the induced polarization parameters is mostly tally with the rich water＇ s actual situation, thus combine these two methods mentioned above can advise the hydrogeological investigation of this work area in an efficient way.
