摘要： 高密度电法是物理勘探新方法的一个重要分支，其以各种地质体的电性差异为基础，通过建立地下稳定电场，并研究电场的分布规律来解决地质问题。近年来，综合物探方法的发展日新月异，高密度电法在工程地质勘察中应用也越来越广泛。依据高密度电法在1000 kV淮河大跨越地质勘察中的物探解释，结合钻探资料进行验证，结果表明高密度电法能准确地划分覆盖层和基岩，并因操作便捷、数据采集量大、地质信息丰富等优势弥补了传统勘探手段的不足。

Abstract: The high density resistivity is an important geophysical survey method. Based on the different electrical resistance of different materials, the subsurface soil conditions can be surveyed by studying the electrical field of the ground. In recent years, the high density resistivity receives wider applications in the geological investigations. This paper presents the high density resistivity survey results for the Huaihe River Crossing Tower for 1000kv UHV Transmission Project. Verified by the test boring data, it is concluded that the high density resistivity method can accurately overburden soil and the bedrock. Compared with other conventional geological investigation methods, such as, test boring, cone penetration test and dynamic cone penetration test, this method has also the advantage of easy to operate, it can also collect a large amount of data and provides rich geological information.
