摘要
为实现工程场地地下结构精细化探测,在研究区开展了工程勘察中常用的四极装置(温纳、施伦贝谢尔、偶极)三种装置类型的三维高密度电法精细化探测对比研究。主要对各装置的三维反演可视化成果及不同方向的切片成果进行了对比分析。研究结果表明:三种装置均能完成浅部地质体的精细刻画,但在数据覆盖范围、探测深度,分辨率等方面存在一定的差异。根据分析结果提出了一种工程场地勘察三维高密度电法野外数据采集装置类型选择方案,对以后三维高密度电法工程实际应用具有一定的参考和指导意义。
In order to achieve fine detection of underground structures in engineering sites,a comparative study of three-dimensional high-density electrical fine detection of three commonly used types of quadrupole devices(Werner,Schlumberger,Dipole)in engineering surveys was conducted in the research area.We mainly conducted comparative analysis on the three-dimensional inversion visualization results of various devices and the slicing results in different directions.The research results indicate that all three devices can achieve precise characterization of shallow geological bodies,but there are certain differences in data coverage,detection depth,resolution,and other aspects.Based on the analysis results,a selection scheme for the type of 3D high-density electrical field data acquisition device for engineering site exploration has been proposed,which has certain reference and guiding significance for the practical application of 3D high-density electrical engineering in the future.
