宝昌地震台地电阻率电性结构特征

使用高密度电法和电测深法,对内蒙古宝昌地震台地电阻率场地进行实地测量,获得该场地电性结构特征参数,判定该台地电测区结构属于KH型,并结合钻孔柱状图,获得该台地下介质水平层状电性结构模型,发现地层厚度呈不均匀分布,总体较为连续、完整,可为今后该台地电阻率异常提取、异常识别及观测精度提高等提供基础数据。

Structural characteristics of electricity of ground resistivity at Baochang Seismic Station

Using high density resistivity method and electrical sounding method, the field resistivity of Baochang Seismic Station in Inner Mongolia is measured and the characteristic parameters of the site electrical structure are obtained. The structure of the electrical survey area of this site belongs to KH type. Combining with the borehole histogram, we obtained the horizontal layered electrical structure model of the underground medium of the station. It was found that the thickness of the stratum was unevenly distributed, which was continuous and complete in general. This study can provide basic data for extracting anomaly of ground resistivity, identifying anomaly and improving observation accuracy.
