Effect of Wetting and Drying Cycles on Swell/Collapse Behavior and Cracks of Fine – Grained Soils

Tikrit Journal of Engineering Sciences, 2011
Many of the soils undergo volumetric changes due to the change in the water content. Swell-shrink and collapse behavior of those soils affects the stress state in soil and the interacted structures.

Impact of wetting-drying cycles on dynamic tensile strength of rock

Thermal Science, 2019
To study the effect of wetting-drying cycles on dynamic tensile strength of rock, dynamic indirect tension test of sandstone samples after 0, 1, 3, and 5 wetting-drying cycles was conducted. Tensile failure was observed by digital image correlation. The result shows that failure appears in the center of the samples initially, consistent with tensile ...

Macro-micro tests of cohesive soil under varied normal and shear stresses subjected to drying-wetting cycles

Journal of Rock Mechanics and Geotechnical Engineering
The mechanical behavior of cohesive soil is sensitized to drying-wetting cycles under confinements. However, the hydromechanical coupling effect has not been considered in current constitutive models.

Loess Strength Prediction Model Under Dry–Wet Cycles Based on the IAGA-BP Algorithm

Applied Sciences
In the long-term operation of canals in loess areas, instability and landslides frequently occur due to the effect of wetting–drying cycles, which severely restricts the long-term safe operation of engineering projects.

Experimental study on the macroscopic and microscopic properties of the sliding zone soil in the Huaipa landslide under wetting-drying cycles

Frontiers in Earth Science
Landslides in the Yellow River basin are frequently triggered by periodic rainfall and groundwater fluctuations, processes that progressively degrade the mechanical properties of sliding zone soil.

The Influence of Rainfall and Evaporation Wetting–Drying Cycles on the Open-Pit Coal Mine Dumps in Cam Pha, Quang Ninh Region of Vietnam

Applied Sciences
Among the slope hazards caused by rainfall, not all of them occur directly during storm washout, and the wetting–drying cycles’ effect on the rainfall–evaporation process is an important cause of shallow slope instability. In this study, taking the slope
