超高密度电阻率法是直流电法勘探一种新的应用,其不受传统的电法装置类型的限制,能够进行地面、井间等方式探测,应用范围广泛。本文对超高密度电阻率法理论模型进行了详细研究,并对模型进行了正反演计算。研究成果在工程中进行了试验验证,采用地面、井间两种方式对溶洞进行了探测,取得了非常好的效果。验证结果表明:该方法探测溶洞具有可行性、有效性,为类似工程应用及进一步的理论研究奠定了基础。
Ultra-high density resistivity method is a new application of direct current method prospecting. It is not limited by the traditional type of electric method device, and can be used to detect ground and well, etc., and has a wide range of applications. In this paper, the theoretical model of ultra-high density resistivity method has been studied in detail, and the forward and inverse calculation of the model has been carried out. The research results were verified in the project, and the caverns were probed with two methods of ground and well, and achieved very good results. The verification results show that this method is feasible and effective for detecting karst caves, which lays the foundation for similar engineering applications and further theoretical research.
