Latent Heat of Frozen Saline Coarse‐Grained Soil

Journal of Geotechnical Engineering, 1985
In recognition of the need to predict the thermal regime in arctic offshore structures, a laboratory research program was constructed to evaluate the latent heat of fusion of a coarsegrained soil w...

Modelling frost heave in unsaturated coarse-grained soils

Acta Geotechnica, 2020
Coarse-grained soils were considered not susceptible to frost heave. However, substantial frost heave has been observed in unsaturated coarse fills in high-speed railway embankments. Recent experimental results in the literature show that vapour transfer has a considerable influence on the frost heaving of coarse-grained soil.

Stiffness of coarse-grained soils at small strains

Géotechnique, 1997
The accurate predictions of deformations around geotechnical structures depend on the correct definition of the stiffness–strain curve of the soil, and in particular on the elastic stiffness at very small strains, which, being the starting point of the curve, may be regarded as a benchmark parameter for a given soil.

Size Distribution of Coarse-Grained Soil by Sedimaging

Journal of Geotechnical and Geoenvironmental Engineering, 2014
AbstractAn image-based method has been developed for determination of particle-size distributions of coarse-grained soils in the 0.075–2.0 mm range. The percentage of fines is also determined. The test is referred to as sedimaging because it analyzes an image of a soil that has been rapidly sedimented through water to sort the particles by size.

Laboratory and theoretical evaluation of impact of packing density, particle shape, and uniformity coefficient on erodibility of coarse‐grained soil particles

Earth Surface Processes and Landforms, 2020
Sedimentation – including erosion, transport, and deposition of coarse‐grained particles – is a primary and growing environmental, engineering, and agricultural issue around the world.

Bimodal Shear-Strength Behavior of Unsaturated Coarse-Grained Soils

Journal of Geotechnical and Geoenvironmental Engineering, 2013
AbstractThe microstructure, compressibility, and shear strength of an unsaturated widely graded coarse soil were investigated through a series of laboratory tests. The results show that coarse soil has a dual-porosity structure that has both intra- and interaggregate pores. The soil-water characteristic curve (SWCC) shows bimodal features. Accordingly,

Temporary Solidification of Coarse Grained Soil by Magnetorheological Fluids

Soil Dynamics Symposium in Honor of Professor Richard D. Woods, 2005
Magnetorheological fluids (MRFs) are suspensions of micron-sized, magnetizable particles in a base fluid such as water, oil, or silicon, that freely transition from fluid to semi-fluid to solid states when subjected to magnetic fields. The pr esent paper explores the usage of MRFs to temporarily solidify coarse -grained soils.

Characteristics of the liquid and vapor migration of coarse-grained soil in an open-system under constant-temperature freezing

Cold Regions Science and Technology, 2019
Liquid and vapor migration is the key factor in evaluating the frost heaving properties of coarse-grained soil (CGS) in the high-speed railway (HSR) subgrade in cold regions.
