黄河水库南屯进行勘查的主要目的就是通过物探方法初步查明地下溶洞存在的情况以及区内的地质概况，为该区地质灾害的评价提供必要的参考依据。通过多种物探方法实验，发现激电中梯、激电联剖及视电阻率测深效果相对较好。由于区内地下水较发育，而且已知塌陷部位都不同程度的含水，水导电性能好。。因此，在地表观测时呈现视电阻率低阻趋势。当溶洞中没有地下水存在时，视电阻率呈现高阻异常。这样就可以通过视电阻率的反映来发现地下溶洞。

The main aim prospecting Huanghe reservoir Nantun ifnds preliminarily the underground caves and geology in the region through geophysical methods, provide the necessary reference for the assessment of geological disasters in the region. It is relatively good results to ifnd the IP intermediate gradient, IP combined proifle and apparent resistivity sounding through the experiment of various geophysical methods. The groundwater is developed, and there is water in the known collapse positions, water conducts electricity well. Therefore, the apparent resistivity is lower when the Surface measurement. When the caves without groundwater, the apparent resistivity shows high resistivity anomaly. It can ifnd the underground caves according to the apparent resistivity values;.
