摘　　要：以安徽黄山市歙县深渡镇约源村汪山组滑坡作为研究对象,在野外踏勘和测绘的基础上,运用高密度电法和大地电磁法联合勘察,并结合钻探验证资料对勘察成果进行分析。研究结果表明:电阻率参数能够很好地反映研究区的地层分布特征及滑坡体的空间分布特征,并通过钻孔资料得到了有效验证;汪山滑坡局部富水,富水区存在水力联系,是滑坡的潜在动力,推断是由于古滑坡受雨水浸入,致使产生斜坡滑移。因此,采用高密度电法以及大地电磁法联合勘察,可以有效地应用于黄山市典型滑坡的勘察中,为进一步开展黄山市滑坡的成因机理和防治研究提供参考数据。Based on field survey and mapping,both of high-density electrical and magnetotelluric methods were applied to the landslide of the Wangshan Formation,Yueyuan Village,Shexian County,Huangshan City,Anhui Province,and drilling data were used for cross check.The results show that the resistivity parameters can well reflect the characteristics of stratigraphic distribution and spatial distribution of the landslide in the study area,which are effectively verified by the drilling data.The Wangshan landslide is locally rich in water,and there is a hydraulic connection in the water-rich area,which is the potential source that drives the landslide.It is inferred that the ancient slope was partly immersed in rainwater,resulting in slope sliding.The joint use of these two methods has been proved effective and provided reference data for furthering research on the formation mechanism and control of landslides in Huangshan City.
