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 ...

Influence of Drying–Wetting Cycles on the Water Retention and Microstructure of Residual Soil

Geofluids, 2022
Due to frequent changes in the humid and hot environment, the residual soil with a particle-size distribution (PSD) from gravel to clay experiences multiple drying–wetting cycles.

Delayed compression and breakage of crushed mudstones due to the drying/wetting and temperature cycles [PDF]

E3S Web of Conferences
Soft sedimentary rocks, especially mudstones, disintegrated or crumbled when subjected to cyclic drying and wetting, known as slaking, which was the cause of severe slope failures and ground settlement.
