| 摘 要： | 可控源音频大地电磁法(CSAMT)具有勘探深度大、分辨率高及抗干扰能力强的优点。为了解浙江省武义县测区地下电性结构,从而查明该区地下水赋存情况,在勘查区布置了两条CSAMT测线,通过对所采集的两条CSAMT剖面数据进行处理与二维反演,获得了工区地下1 km以浅的电性分布特征。并结合该区地质与水文资料得出了CSAMT与水文工程地质联合剖面图,推断出了不同地层分界面及断裂构造深部延展情况,为该区下一步的地下水钻孔工作提供了有效的参考依据。

| Abstract: | Controlled source audio magnetotelluric method(CSAMT)has the advantages of large exploration depth,high resolution and strong anti-interference ability.In order to obtain the subsurface electrical structure of the survey area in Wuyi county,Zhejiang province,two CSAMT survey lines were arranged in the area.By processing and collecting two-dimensional inversion of the CSAMT data,the electrical structures from surface down to the area about 1 km in the prospecting area are obtained.With geological and hydrological settings in this area,the joint profile of CSAMT and hydro-engineering geology is obtained,and the extension of different stratigraphic interfaces and fault structures is inferred,which confirms the feasibility of further drilling for groundwater exploitation in this area. |
