【摘要】 高密度电法具有较好的垂向分辨率,联合剖面法具有较好的水平分辨率,结合某核电厂选址勘察的实例,证实了综合电法勘探能够提高资料处理的精度。两种方法具有一定的互补性,在后期资料解译时,采用高密度电法划分岩层风化界面和查找隐伏构造;利用联合剖面法确定电性差异界面的位置和特征,从而更加准确地把握场地的地质条件,为核电厂选址勘察提供直观的地层及构造特征。更多还原

【Abstract】 High density resistivity method has better vertical resolution and combined profiling method has better horizontal resolution.Taking site selection investigation of a nuclear power plant as an example,it verifies that the comprehensive electrical prospecting can improve the accuracy of data processing.Two methods have some complementation.In the later data interpretation,high density resistivity method is used to divide rock weathering interface and find hidden structures,combined profiling method is used to determine the location and characteristics of interface with electrical difference.So it can get the site geological conditions more accurately,and it provides more intuitive understanding of stratum and structure features for site selection investigation of a nuclear power plant.更多还原
