摘　　要：高密度电阻率法是一种成熟的工程物探方法,广泛应用于地质灾害调查。废弃矿山在不良天气条件下容易产生滑坡地质灾害。对由废弃渣石、杂填土人工堆积形成的滑坡体进行勘察,研究高密度电阻率法在该环境下的勘察效果。通过对视电阻率反演断面图分析,推断滑动面深度、滑床起伏形态等滑坡体地质结构信息,为废弃矿山滑坡灾害治理设计提供依据。钻探验证表明,高密度电阻率法有效的推断出滑坡体滑动面深度、滑床起伏形态信息,可用于废弃矿山滑坡灾害勘察。The high density resistivity method is a mature method of engineering geophysical prospecting,which is widely used in geological hazard investigation.Abandoned mines are easy to cause landslide geological disasters in bad weather conditions.The landslide formed by artificial accumulation of waste slag stone and miscellaneous filling soil have been investigated,and the investigation effect of high density resistivity method in this environment has been studied.By analyzing the cross section map of resistivity inversion,geological structure information,such as the depth of sliding surface and the shape of sliding bed have been deduced,which provides the basis for the design of landslide control in abandoned mines.The drilling verification shows that the high density resistivity method can effectively infer the depth of sliding surface and the fluctuation pattern of slide bed,and can be used for landslide hazard investigation in abandoned mines.
