摘　　要：准确地找出滑动面是滑坡勘查最重要的目的之一,传统的勘探方法工作量大、费用高且耗时较长,地球物理勘查能较好地弥补这些不足。本文应用高密度电法对广西两处典型浅层土质滑坡进行勘探,选用合适的装置及参数,得到滑坡区各层岩土体的电性特征,结合地质资料推断解译,得到了滑坡区岩土层的结构特征及滑动面的形态、埋深等数据。经钻孔验证,高密度电法推断与钻探结果基本一致。实践证明,高密度电法能较好地反映出浅层土质滑坡区地下岩土情况,为滑坡的预测及治理设计提供依据,同时也可为后期类似的滑坡勘查提供技术参考。Accurately identifying the sliding surface is one of the most important objectives of landslide investigation.Traditional exploration methods are large workload,high cost and time-consuming,while geophysical exploration can effectively make up for these shortcomings.This paper applies the high-density electrical method to explore two typical shallow soil landslides in Guangxi.By selecting appropriate devices and parameters,the electrical characteristics of various layer of rock and soil bodies in the landslide area are obtained.Combined with the inferred interpretation of the geological data,the structural characteristics of the rock and soil layers in the landslide area and the data on the morphology and burial depth of the sliding surface are obtained.Verified by drilling,the high-density electrical method inferred is basically consistent with the drilling results.Practice has proven that the high-density electrical method can effectively reflect the underground rock and soil conditions of shallow soil landslide areas,which can provide a basis for landslide prediction and management design,and offer technical references for the later similar landslide investigations.
