Measuring the Content of Unfrozen Water in Frozen Soil Based on Resistivity

open access: yesInternational Journal of Electrochemical Science, 2020
This study proposes a new method for calibrating the theoretical model of resistivity versus unfrozen water content in frozen soils. The method characterizes correlations between the soil mass resistivity and unfrozen water content in the frozen state by

Influence of soil resistivity on stray current in power supply system of urban rail transit

open access: yesJournal of Measurement Science and Instrumentation, 2022
In order to explore the influence of soil resistivity on stray current in power supply system of urban rail transit, we establish an equivalent circuit model of the rail-to-ground structure based on resistance network method first.

Effect of Wetting-Drying Cycles on Mechanical Behaviour and Electrical Resistivity of Unsaturated Subgrade Soil

open access: yesAdvances in Civil Engineering, 2019
Compacted soil is widely used in road and railway subgrade, while alternation of seasons can cause fluctuations in moisture content of soil (i.e., wetting-drying cycles) and influence the performance of soil.

Resistant ultralaminae in soils [PDF]

open access: yesOrganic Geochemistry, 1996
Observation of a chemically resistant organic residue from maize crop soils by transmission electron microscopy reveals the occurrence of thin laminae with 10-50 nm thickness, similar to resistant, highly aliphatic biopolymers found in kerogens and microbes.
