Mechanical Behavior and Deterioration Mechanism of Sandstone Under Acidic Wetting–Drying Coupling Effects
Acidic wetting–drying cycles can progressively deteriorate sandstone used in rock engineering, but the link between macroscopic mechanical degradation and three-dimensional pore-crack evolution remains unclear. The objective of this work was to clarify the deterioration mechanism of sandstone under repeated acidic wett...

Mechanical and disintegration behaviors of carbonaceous rock under drying-wetting cycles
Effects of drying-wetting cycles and loads on the mechanical and disintegration characteristics of carbonaceous rock were investigated by triaxial compression tests and disintegration tests in this study. The disintegration phenomena of carbonaceous rock exposed to drying-wetting cycles were analyzed, and the correspon...

Effect of pore structure response on compressibility characteristics of a preloaded soft clayey soil under dry-wet cycles
ABSTRACT The stabilization of soft ground is essential before construction, with preloading being a widely used mechanical method. This study investigates the combined effects of preloading and cyclic drying–wetting (D–W) on the pore structure and compression behaviour of soft clay. Remoulded specimens (0 kPa) and spec...

Multi-scale mechanical behaviour of XG–EICP reinforced calcareous silt under wet-dry cycles
Calcareous silt is susceptible to degradation under climatic variations, particularly wetting–drying (W-D) cycles. This study investigates the synergistic effects of xanthan gum (XG) and enzyme-induced carbonate precipitation (EICP) on the shear strength of calcareous silt under varying moisture contents and W-D cycles...

Investigation of Mechanical Degradation and Microstructural Evolution of Red-Bed Soft Rocks Under Wetting–Drying Cycles
To clarify the water-sensitive deterioration mechanisms of red-bed soft rocks under repeated wetting–drying cycles, mudstone samples from two representative sites in the Sichuan Basin were investigated through multiscale experiments combining mechanical testing, X-ray diffraction (XRD), and scanning electron microscopy...

Non-Monotonic Mechanical Response and Multiscale Damage Evolution of Argillaceous Siltstone Under Wet–Dry Cycles
Argillaceous siltstone forms water-sensitive weak layers in red-bed slopes, but its multiscale deterioration under wet–dry cycling remains incompletely understood. Specimens subjected to 0, 1, 3, 5, 7, and 9 cycles were examined through uniaxial compression, energy analysis, digital image correlation (DIC), and microst...
