摘要
高密度电法具有测点密度大、采集速度快、抗干扰性强等特点,被广泛应用于滑坡等地质灾害治理和工程勘察中。测量过程中,通过将横向电剖面法和纵向电测深法相结合,形成阵列式勘探,获取丰富的地电信息。本文介绍利用该方法对勘查区的滑坡区域进行勘查,通过解译地电成果图获得了滑坡体纵、横向发育及展布情况,查明滑坡体空间形态特征、滑动面埋深以及与滑坡发育相关的断裂情况等,反映了该方法在滑坡地质灾害治理中的实际应用效果,对后期工程钻探起到了很好的指导作用。
With the characteristics of large density of surveying points, fast gathering speed and strong anti-interference, high density resistivity method is widely applied to geological disasters such as landslide governance and engineering inverstigation. In the process of measuring, through the combination of horizontal resistivity and vertical electrical sounding method, and then forming the array type exploration, abundant geoelectric information can be obtained. This paper introduces the use of this method to explore the landslide area exploration. By the interpretation of the electric drawing, the develpement and distribution of vertical and horizontal situation of landslide are obtained. The landslide space forming features, the embedded depth of sliding surface, the fault related to the landslide development and etc. are found out. Except that, this method provides a good guiding role for drilling engineering later in landslide geological disaster governance.
