摘要/Abstract

摘要： 在高黏粒含量海洋土中，黏粒吸附孔液中阳离子形成的双电层会直接影响土体导电性，与孔液、土体结构共同形成土体导电性的影响因素，使导电结构变得复杂。对饱和的海洋土而言，固结程度不同代表了土体结构不同。为量化分析双电层对不同固结程度高黏粒含量海洋土导电性的影响，界定电阻率测试技术对海洋土结构变化的反映能力，分别以黄河三角洲和南海北部陆坡海洋土为研究对象，进行电阻率和其他物理性质测试。基于测试结果分析不同黏粒含量海洋土电阻率的变化规律和独有特征，借鉴黏性土多元导电理论构建适合的电阻率模型。研究表明，黏粒含量对不同固结程度海洋土电阻率的影响不同，根据其变化特征可分为3个阶段：正常固结的海洋土电阻率变化可用简化的二元模型公式表示，当孔隙度小于50%时，电阻率随孔隙度呈明显的幂函数降低，当孔隙度介于50%~60%时，电阻率随孔隙度降低速率明显减小；欠固结海洋土孔隙度均高于60%，电阻率随孔隙度线性减小，可用线性模型公式描述。电阻率测量技术对高黏粒含量正常固结海洋土结构变化（孔隙度变化）反映能力良好，探测灵敏度可达25 Ω·m；对欠固结海洋土结构变化反映困难。

Abstract: The clay adsorption cations in pore fluid can form a double electric layer, which affects the soil conductivity, and together with pore fluid and soil structure make the conductive structure complicated. To address this issue, the resistivity values and other physical properties of soil from the Yellow River Delta and the northern South China Sea slope were tested. The results show that the effects of clay content on the resistivity of marine soil with different consolidation degrees are different. The resistivity characteristics of marine soil can be divided into 3 stages. The variation of resistivity of normally consolidated marine soil can be expressed by simplified binary model formula. When the porosity was less than 50%, the resistivity was power function reduction, when the porosity was between 50% and 60%, the resistivity decreased slowly with the decrease of porosity, when the porosity of unconsolidated marine soil was higher than 60%, the resistivity decreased linearly with the porosity,which can be described by the linear model formula. The resistivity testing technology has a good ability to reflect the changes of the normally consolidated soil structures (porosity) with high clay content, and the detection sensitivity is up to 25 Ω·m; however, it is difficult to reflect the changes of the unconsolidated marine soil.

Key words: marine clay, resistivity characteristics, resistivity model, influencing factors
