Anisotropic behavior of high liquid limit clay subjected to two maximum drying stress paths

Thermally induced transition from expansive clay to a frictional granular state: An experimental investigation

Expansive soils pose persistent challenges to geotechnical design due to their high swelling potential and sensitivity to moisture variations. Thermal stabilization has recently emerged as a promising alternative to conventional chemical treatment, yet its implications for soil strength mechanisms remain insufficiently...

A Multiscale Experimental and Constitutive Study of Silt–Clay Transition Soils

This study investigates the macromechanical behavior and microstructural features of synthetic silt–clay mixtures spanning a plasticity index range of 9.8%–31%, with emphasis on how pore-size distribution and fabric anisotropy provide microstructural insights into the macrobehavior described by constitutive laws. I...

Assessment of Collapse Behavior and Post-Collapse Compressibility Response of Soft Clay under Repeated Drying–Wetting 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...

Thermal–Induced Fracture Mechanics Characteristics of Sand–Bentonite Composites

Numerical Study of Failure Mechanism and Effectiveness of Control Measure of Soft Rock Roadways Affected by Humidity Diffusion

Understanding the failure mechanism of soft rock roadways in high-humidity environments, as well as designing appropriate control measures, are critical for ensuring their stability. In this study, swelling and triaxial compression tests on argillaceous sandstone were first performed. Results show that the triaxial com...
