摘要 高密度电阻率法是以岩、矿石的电性差异为基础,通过探测场的参数变化获得电性局部差异,从而认识被测目标的一种勘探手段。阐述了高密度电阻率法测定覆盖层厚度的工作原理、方法及其数据的处理分析过程,并将其应用于工程实践。实例分析表明,该方法对测定覆盖层的厚度具有较好效果,且具有成本低、效率高、测试简便等优点,因此其在工程应用方面具有一定价值。 High density resistivity method is a kind of exploration which regards the electricity difference of the rock and mineral as the foundation, by observation and study of the distributing regulation of underground stable electric field to resolve the mineral resources, environment and engineering geology problem, and by probing into the variety of field parameter to obtain the partial difference in electricity and to understand the measured target. This method can determine the overcast thickness by making use of the electricity difference between overcast layer and lower datum rock, which is one of the most valid methods for the high-efficiency, deep and accurate ground electricity section imaging. This article explained how to measure overcast thickness, method and the process of data processing and analyzing, and applied it to actual engineering. The actual application indicated that this method can get good result of measuring the overcast thickness, and is of low-cost, high-efficiency and simple characters, therefore it has the certain value in engineering application.
