| 中文摘要: |
| 岩溶在我国分布很广泛，溶洞作为岩溶地区最大的危害通常存在不同的充填类型。高密度电阻率法勘探作为溶洞探测的重要方法，在岩溶地区被广泛使用，实际工作中通常需要采取相应的装置类型。本文对比了不同装置类型下不同充填类型溶洞的地电学特征，分析其正反演结果。结果表明：不同充填类型的溶洞，应当采用不同的高密度电法探测装置。当溶洞的充填类型不确定时，可采用偶极-偶极(Dipole-Dipole)装置进行探测，该装置对三种不同充填类型的溶洞均有较好的效果。 |
| 英文摘要: |
| Karst is widely distributed in China, which has different filling types, and may lead to serious geologic hazard. As an important tool of karst cave exploration, the high-density resistivity method is often used in karst areas. In practical work, corresponding device types are usually needed to choose appropriately. This paper compares the geoelectric characteristics of different filling types under different device types, and analyzes forward modeling and inversion results from them. The results show that different high density electrical detection devices should be applied to different filling types of karst caves. When the filling type of the cave is uncertain, the dipole-dipole device is preferably chosen to detect the cave, which will achieve a good effect in exploration of three different filling types of caves. |
