Abstract

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
