摘　　要：堆积体是在中国西南高山峡谷区修建水电工程中常见的不良地质体,其主要由崩积或滑坡堆积物等组成,稳定性对地质应力较为敏感,天然状态多处于极限平衡,其稳定问题常是坝址选择、工程治理或地质灾害评估的重点研究对象。该文通过部分工程实例,说明采用连续电导率剖面法(EH4)在确定堆积体的规模、大小、埋深、下界面等方面的效果。Accumulated bodies are bad geologic body common in building hydroelectric station in deep gorge area of southwest China and mainly consist of accretions from landslide, its stability is sensitive to geologic press and natural situation mostly is extreme balance that is key studied object in selection of embankment site, control by engineering or evaluation of geologic hazards. The paper, taking a part of engineering cases, illustrated the effects using continuous conductivity profile method to determine the scope, size, buried depth and underlying interface of accumulated bodies.
