摘　　要：利用音频大地电磁测深(AMT)与高密度电阻率相结合的方法,在辽宁新城子深井进行地电阻率观测,探测地下电性结构分布情况。通过精细探测,圈定了含水区的空间位置、范围和形态等关键参数,为多极距多层地震地电阻率场地选择和设计提供了重要参考。Using a combined method of audio-frequency magnetotellurics(AMT)and high-density resistivity,resistivity observations were conducted in the deep well of Xinchengzi,Liaoning,to investigate the distribution of underground electrical structures.Through detailed exploration,critical parameters such as the spatial location,range,and morphology of the aquifer zone were delineated,providing valuable references for the selection and design of multi-pole distance multi-layer earth resistivity sites.
