Electrical resistivity evolution of compacted silty clay under drying−wetting cycles sequentially coupled with dynamic loads

open access: yesRock and Soil Mechanics, 2021
The performance evolution of subgrade soil under the coupling effect of drying?wetting cycle and dynamic load is essential for the safety and stability of the subgrade.

Sandstone Slope Stability Analysis Under Wetting-Drying Cycles Based on Generalized Hoek-Brown Failure Criterion

open access: yesFrontiers in Earth Science, 2022
The deterioration of rock strength due to cyclic fluctuations in the groundwater level in drawdown regions influences bank slope stability. Based on wetting–drying cycling and uniaxial compression tests of sandstone specimens, the intact rock strength ...

Dry/Wet Cycling and the Thermodynamics and Kinetics of Prebiotic Polymer Synthesis [PDF]

open access: yesLife, 2016
The endoergic nature of protein and nucleic acid assembly in aqueous media presents two questions that are fundamental to the understanding of life’s origins: (i) how did the polymers arise in an aqueous prebiotic world; and (ii) once formed in some manner, how were they sufficiently persistent to engage in further chemistry.

Dry–wet cycles increase pesticide residue release from soil [PDF]

open access: yesEnvironmental Toxicology and Chemistry, 2012
AbstractSoil drying and rewetting may alter the release and availability of aged pesticide residues in soils. A laboratory experiment was conducted to evaluate the influence of soil drying and wetting on the release of pesticide residues. Soil containing environmentally long-term aged (9–17 years) 14C-labeled residues of the herbicides ethidimuron (ETD)

Impact of drying-wetting cycles on the small strain behaviour of compacted clay

open access: yes, 2023
Small strain shear modulus (Gmax) is an important parameter for assessing the performance of compacted soils that underlie typical transport infrastructure assets such as railway tracks.

Impacts of drying–wetting cycles on rhizosphere respiration and soil organic matter decomposition [PDF]

open access: yes, 2013
Drying-wetting cycles influence both soil organic matter (SOM) decomposition and rhizosphere processes. Rhizosphere processes also affect SOM decomposition through rhizosphere priming. However, little is known about how drying-wetting cycles regulate SOM

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.
