不同类型滑坡体的高密度电阻率法勘察电性特征
|
摘要
中国西南地区滑坡灾害严重,滑坡勘察中判断滑坡体类型、规模等非常重要。文中总结了滑坡体的不同分类方法及电性特征,通过对20多个滑坡体的高密度电阻率法勘察资料进行综合分析,明确了不同类型滑坡体的电阻率特征差异明显;重点介绍了土质滑坡、岩石滑坡和破碎岩石滑坡等3个高密度电法探测实例的异常特征。实践证明,利用高密度电阻率法能从电阻率异常特征来推断滑坡体的类型、物质组成,其结果对滑坡体勘察及后期治理、钻探施工起到指导作用。
The landslide in southwest China has caused serious casualties and huge economic and property losses. It is very important to determine the type and scale of landslide. First,this paper introduced the principle and data processing method of high density resistivity method. Second,we summarized the different classification methods and physical characteristics of the landslide. Finally,through the comprehensive analysis of more than 20 landslide survey data obtained by high density resistivity method,it is held that the apparent resistivity characteristics of the different types of landslide are different obviously. With practical examples,this paper mainly deals with three abnormal characteristics of high density resistivity method detection,i.e.,the soil landslide,rock landslide and broken rock landslide. It is proved that the high-density electrical method can deduce the type and material composition of the slope from the abnormal characteristics of the apparent resistivity,and provide guidance and demonstration for the investigation of the landslide body and the later management and drilling construction.
