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1000kV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。
The high-density electrical method is an important branch of the new physical exploration method. Based on the electrical difference of various geological bodies, the high-density electrical method solves the geological problems by establishing the underground stable electric field and studying the electric field distribution law. In recent years, the rapid development of integrated geophysical methods, high-density electrical method in engineering geological prospecting is also more and more widely used. Based on the geophysical interpretation of the high-density electrical method in the 1000kV Huaihe Long-span Geological Prospecting and the verification of the drilling data, the results show that the high-density electrical method can accurately classify the overburden and bedrock and is characterized by convenient operation, large amount of data acquisition, Information rich and other advantages to make up for the lack of traditional means of exploration.
