摘　　要：高密度电法采用阵列式的数据采集方法,野外工作便捷、效率较高,数据处理和成果解释方便,可以快速得到地质成果,在不稳定斜坡等地质灾害前期勘察工作中具有很高的时效性,应用较广泛。文章采用高密度电法对南邑村不稳定斜坡中存在的空洞填埋、坍塌等隐患区进行了较为全面的排查,主要是为了探查勘察区浅部工程地质情况,大致推断隐患区空洞填埋、坍塌及地层变化情况。依据高密度电法剖面图基本查明了电性分布特征,较为准确地推断了隐患区位置,为后期综合治理工程提供了依据。The high-density electrical method adopts array data acquisition method,which is convenient and efficient in field work.It is convenient in data processing and interpretation of results and can quickly obtain geological results.It has high timeliness and wide application in the early exploration work of unstable slopes and other geological disasters.This article uses high-density electrical method to conduct a comprehensive investigation of hidden danger areas such as cavity landflling and collapse in the unstable slope of Nanyi Village.The main purpose is to explore the shallow engineering geological conditions of the survey area and roughly infer the situation of cavity landfilling,collapse,and stratigraphic changes in the hidden danger areas.Through this work,the electrical distribution characteristics have been basically identified based on the high-density electrical profile,and the location of hidden danger areas has been accurately inferred,providing guidance for the later comprehensive treatment project.
