高密度电法在查明潜伏断裂中的应用

Application of High Density Resistivity Method to Hidden Fault Investigation

高密度电法基本原理与传统电阻率法相同,所以高密度电法也被称作是直流高密度电阻率法。近年来该方法被广泛的应用在重大场地的工程地质调查、坝基及桥墩选址、采空区及地裂缝探测等众多工程勘察领域。本文阐述了应用高密度电法对一个国家重大建设项目工作区域内可能存在的断层进行勘查,并进行了钻探,经比对取得了较好的地质效果。查明了工区中存在较大型的断层,对工程项目具有较大指导意义。

The basic principle of high-density resistivity method is the same with the traditional resistivity method, so the high - density resistivity method is also called the DC - high density resistivity method. In recent years, this method is widely used in the major engineering geology survey, dam bridge piers and site selection, mined-out area, geosuture detection and many other engineering survey areas. This paper expounds the application of high - density electrical method in a major state construction project work areas which pos sibly exist fault. After the drilling, the good geological effect is gained through the comparison and it also found out that there exist faults in the work areas.
