Study on the Mechanical Behaviour of Unsaturated Silty Sand and Pavement Response Under Moisture Variations
Drainage has been widely adopted in pavement structures. Due to drainage, wetting and drying, subgrade soils may be subject to conditions ranging from saturation to partial saturation (unsaturated). Particularly, unsaturated soil exhibits matric suction in contrast to saturated soils. Matric suction can impact the mech...

Dynamic Mechanical Properties and Constitutive Model of Saturated Frozen Soil with Different Pore Ratios
This study investigates the dynamic stability of frozen soil slopes subjected to strong disturbances such as blasting. Dynamic compression tests were conducted on saturated frozen clay specimens using a split Hopkinson pressure bar system. The effects of strain rate (100–700 s−1), temperature (−15°C, −23°C, and −30°C...

Effect of Glauconite Content on the Compression and Shear Behavior of Sand
Glauconite sand presence at several offshore wind lease areas in the United States and Belgium has raised geotechnical concerns due to their high crushability and potential for clay-like behavior, introducing uncertainty in pile installation resistance and axial response. Field experience suggests that even relativ...

Shear strength behavior of frozen unsaturated sands under thermal loads
Understanding the mechanical behavior of frozen unsaturated sand under thermal gradients is crucial for the design and maintenance of infrastructure in permafrost regions. In this study the shear strength of Ottawa sand under varying temperatures, degrees of saturation, and loading conditions is investigated. A ser...

Drying soil-water characteristic curve of compacted kaolin prepared at optimum water content and saturated under free swelling
Water retention and deformation evolve simultaneously during drying, making their interaction an essential aspect of the hydro-mechanical behaviour of compacted unsaturated soils, particularly when deformation is not mechanically constrained. This study investigates the drying soil-water characteristic curve (SWCC) of...

Dynamic Response of Saturated Kaolin Clay under Repeated Impact Loading
The dynamic response mechanism of clayey foundations under impact loading remains insufficiently understood. This study investigates the dynamic behavior of saturated kaolin clay under repeated one-dimensional impacts using an improved Split Hopkinson pressure bar (SHPB) apparatus. Tests were conducted under different...
