高密度电法在某固废堆场防渗墙渗漏勘察中的应用

Application of high-density resistivity method in leakage investigation of a cut-off wall in a solid waste yard

高密度电法是一种集测深法和剖面法于一体的电法勘探方法,具有测点密度大、施工效率高、对探测目标体分辨率高等优点,在工程物探领域得到了较为广泛的应用。本文介绍应用高密度电法在马鞍山市某固废堆场的防渗墙进行渗漏勘察,经过数据处理,得到视电阻率等值线断面图进而圈定低阻异常区域,成功探明渗漏部位,并对渗漏部位进行有效治理修复,阐明了该方法在这一工程勘察领域是一种有效勘探方法。

High-density electrical method integrates depth sounding and profiling, has advantages of high density of measuring points, high construction efficiency and high resolution of the detected target, and has been widely used in the field of engineering geophysical exploration. This paper introduces the high density electrical method applied in the leakage investigation of a cut-off wall in a solid waste yard in Ma’anshan City. After data processing, the apparent resistivity isoline section is obtained, the area of low-resistivity anomaly is delineated, and the leakage part is successfully identified, and effectively treated and remediated, indicating that this method is effective in this engineering investigation field.
