高密度直流电法在高速公路滑坡探测中的应用

Application of High Density Resistivity Method in Highway Road Landslide Prediction

简要阐述了滑坡体对营运高速公路的危害以及探测滑坡体地质特征的重要意义。介绍了高密度直流电法这一新型阵列电探方法的工作原理及方法,并结合工程实例运用α、β、α2电极排列方式对公路滑坡体进行探测,通过对探测数据格式转换、二维反演,输出二维地电断面图,根据地电断面图的特征推测出滑坡体的覆盖层厚度和滑移范围,为全面有效治理滑坡体提供依据。

This article briefly introduces disserve of landslide in the highway road and the significance to explore the geologic characteristics of the landslide. The paper introduced working principle of the high density resistivity method which is a new type of array electricity exploring method. In Combination with the landslide cases , α,β,α2 electrode array modality was adopted for gathering data. The computer was used to transform the exploration data and carry through 2 - D reversion to obtain the 2 - D section chromatogram. On the basis of the landslide characteristics, the overburden thickness and surface parameter were calculated. All these provide the basis for fathering the landslide effectively.
