Abstract

Soil resistivity testing has emerged as a crucial tool for assessing soil corrosivity and informing corrosion control strategies. This review paper aims to explore the limitations of soil resistivity testing and provide insights into alternative methods for accurate measurements and assessment. The paper reveals the challenges associated with surface electrode placement, depth limitations, soil heterogeneity, and the influence of surrounding structures and vegetation. It also discusses potential interference and error sources in soil resistivity testing. To overcome these limitations, alternative electrode configurations, advanced placement techniques, and integrated geophysical approaches were explored. The paper revealed the importance of addressing electrical interference and noise, electrode contact resistance, and equipment limitations in resistivity testing. Additionally, it compared pH testing, corrosion coupons, corrosion inhibitors, and cathodic protection. While these techniques offer advantages, they also have limitations, and the limitations presented in this correspondence are argued to exist provided the soil resistivity displays using present techniques.

回顾用于加强腐蚀控制的土壤电阻率测试：通过综合地球物理方法和替代方法克服局限性

土壤电阻率测试已成为评估土壤腐蚀性和制定腐蚀控制策略的重要工具。这篇综述论文旨在探讨土壤电阻率测试的局限性，并深入探讨准确测量和评估的替代方法。论文揭示了与表面电极放置、深度限制、土壤异质性以及周围结构和植被影响相关的挑战。论文还讨论了土壤电阻率测试中潜在的干扰和误差源。为了克服这些限制，论文探讨了替代电极配置、先进的放置技术和综合地球物理方法。论文揭示了解决电阻率测试中的电气干扰和噪音、电极接触电阻和设备限制的重要性。此外，论文还比较了 pH 值测试、腐蚀试样、腐蚀抑制剂和阴极保护。虽然这些技术具有优势，但它们也有局限性，本报告中提出的局限性被认为存在于使用现有技术显示的土壤电阻率中。
