Mechanical properties and multi-factor ANOVA of reef limestone under cyclic loading after temperature-CO2 pressure dissolution
Reef limestone, as a crucial geological foundation for marine engineering, faces significant challenges regarding its long-term mechanical stability under complex marine environments. To address the coupled effects of chemical dissolution and periodic wave loading in deep-sea and island reef engineering, this study con...

Fracture evolution of micritic bioclastic limestone under Brazilian splitting: a comparison between natural and water-saturated states
The tensile strength properties and the initiation and propagation of tensile cracks within micritic bioclastic limestone–which forms the surrounding rock mass at the tunnel exit of the Altash Water Conservancy Project–pose a threat to engineering stability. To investigate the differences in tensile strength and stress...

Mechanical Properties of Limestone Under Different Confining Pressures and Wet–Dry Cycles
During the operation of large reservoirs, slope rock masses at different elevations are subjected to confining pressure variation and alternating wet–dry cycles induced by water-level fluctuations, resulting in the evolution of their mechanical properties. To investigate this issue, conventional triaxial compression te...

Deterioration Mechanism and Constitutive Model of BFRC Corroded by Acid Rain
To elucidate the long-term degradation mechanism of basalt-fiber-reinforced concrete (BFRC) subjected to acid rain corrosion, this study conducted mechanical tests on BFRC specimens with a fiber content of 0.15% under simulated acid rain (pH = 3.0) over 0–120 corrosion cycles. Results reveal a nonlinear evolution in bo...

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...

A thermo-mechanical constitutive model for fine-grained soils under cyclic and monotonic loading
Geothermal systems and geostructures, as sustainable energy sources, undergo daily and seasonal temperature fluctuations that significantly influence their mechanical response. Reliable prediction of thermally induced deformations therefore requires advanced thermo-mechanical constitutive models. Existing approaches of...
