Experimental Study on the Triaxial Compression Properties of Coarse-Grained Filling Soil under Drying–Wetting Cycles

Geofluids, 2022
To explore the mechanical properties of coarse-grained filling soil in the hydrofluctuation belt of the Baihetan reservoir, a fast drying–wetting cycle method for large-scale triaxial tests was developed and a series of large-scale triaxial compression ...

Effect of Drying-Wetting Cycles on Engineering Properties of Expansive Soils Modified by Industrial Wastes

Advances in Materials Science and Engineering, 2020
The swelling properties of expansive soils can be reduced by the addition of modifiers. Nevertheless, the performance deterioration after modification occurs when weathering for a long term.

Laboratory and Centrifuge Model Tests on Influence of Swelling Rock with Drying-Wetting Cycles on Stability of Canal Slope

Advances in Civil Engineering, 2018
This study focused on the swelling behavior of swelling rock from canal basement under multiple drying-wetting (D-W) cycles. A series of laboratory tests were conducted on a swelling rock, with the cracking and strength behaviors investigated.

Visualizing RNA polymers produced by hot wet-dry cycling [PDF]

Scientific Reports, 2022
Abstract It is possible that the transition from abiotic systems to life relied on RNA polymers that served as ribozyme-like catalysts and for storing genetic information. The source of such polymers is uncertain, but previous investigations reported that wet–dry cycles simulating prebiotic hot springs provide sufficient energy to drive ...

Moisture transport in concrete during wetting/drying cycles

Chemistry and Materials Research, 2013
An accurate description of moisture transport in concrete is significant to determine the service life of a concrete structure. Many authors managed to describe the global moisture transport in concrete during wetting/drying cycles by using Fick’s laws ...

Sustained wet–dry cycling on early Mars

Nature, 2023
The presence of perennially wet surface environments on early Mars is well documented1,2, but little is known about short-term episodicity in the early hydroclimate3. Post-depositional processes driven by such short-term fluctuations may produce distinct structures, yet these are rarely preserved in the sedimentary record4.

Volume Changes and Mechanical Properties of Expansive Mudstone below Canals under Wet‐Dry/Wet‐Dry‐Freeze‐Thaw Cycles [PDF]

Advances in Civil Engineering, 2021
The complex environment in northern China is the main reason for degradation of expansive mudstone below the canals, which resulted in instability and damage of canal slopes. In this study, a serial of laboratory tests was conducted to explore the volume changes and mechanical behaviors of expansive mudstone below the canals in Xinjiang.

Dynamic strength of fly ash-modified loess subgrade under influences of drying-wetting cycle

Yantu gongcheng xuebao, 2020
The traffic load and the drying-wetting cycle have an important influence on the strength characteristics and stability of fly ash-modified loess subgrade. To illustrate the influences of drying-wetting cycle on the strength of the fly ash-modified loess,
