Progressive Damage of Sandstone and Shale Under Heating and Cooling Cycles: Implications for Stratified Rock Slope Stability

Thermally induced cracking and the evolution of mechanical anisotropy in bedded sandstone under high-temperature conditions: a microscale perspective

Monitoring of structures in shaly rock formation

Shaly rock formations, particularly those rich in expansive clay minerals, pose unique geotechnical challenges for infrastructure development. These formations are susceptible to volumetric swelling and deformation when subject to water ingress, mechanical stress and salt concentration, which can lead to progressive st...

Moisture-induced degradation of clay-bearing sandstone

Clay-bearing sandstones used in the construction of historic monuments, churches, and castles are highly susceptible to contour scaling, which manifests as fractures parallel to the exposed facades. Repeated wetting–drying cycles accelerate material degradation through stiffness reduction and hygric deformation induced...

Mechanical and hydraulic properties of fractured Bentheim sandstone at different laboratory-simulated depths

Understanding how rock properties change with depth is crucial for a variety of geoengineering applications. Even rocks that are homogenous at both micro and macro scales, such as Bentheim sandstone, lose this characteristic once fractured. While recent studies have shown how concomitant changes in stress, temperature...

Strength Deterioration of Strongly Altered Granite Under Varying Water Content and Seepage Pressure: Experimental Insights for Reservoir Slope Stability

Reservoir landslides pose a persistent threat to the safe operation of hydropower projects, particularly where altered rock masses within water-level fluctuation zones undergo repeated wetting–drying and seepage-induced deterioration. This study investigates the mechanical behavior and long-term strength evolution of a...

Weathering-Induced Strength Degradation and Hydro-Mechanical Controls on the Stability of Multilayered Tropical Rock Slopes

Tropical environments accelerate rock weathering, which can significantly reduce the stability of mineralized slopes. This study investigates the influence of weathering and groundwater conditions on the stability of a strong–weak–strong multilayered rock slope hosting an iron deposit in the Philippines, where intense...
