摘　　要：为查明枯木拔里水库深厚覆盖层厚度,采用多种物探技术结合的方法进行探测。先采用微动法、EH4音频大地电磁法对物探剖面进行定性解释;再通过大极距四极电测深法进行复核定量解释。结果表明,综合物探方法在深厚覆盖层探测中应用效果明显,解释精度超过90%,具有工程实用价值。In order to determine the thickness of the deep and thick overburden layers in the Kumubali Reservoir,a combination of multiple geophysical techniques was employed for detection.Qualitative interpretation of the geophysical profiles was initially conducted using the microtremor method and the EH4 audio-frequency magnetotelluric method.Subsequently,quantitative interpretation was carried out using the large electrode spacing four-pole electrical sounding method.The results indicate that the comprehensive geophysical methods applied in the detection of deep and thick overburden layers are highly effective,with an interpretation accuracy exceeding 90%.These findings hold significant practical value for engineering applications.
