Investigations on the Effects of Microorganisms on Coarse Grained Soil
2017The association of soil and microorganisms is known to be existent since the formation of earth. However, conventional geotechnical engineering practices has only considered mechanical loading on the soil without taking into account of the biological aspects that might be associated.

Mechanical properties of frozen coarse-grained soils
Engineering Geology, 1981Coarse-grained soils are extensively used in hydraulic engineering, highway and underground construction practice. Many problems in predicting the behaviour of underground structures constructed by artificial freezing, and of soil structures built on frozen soils, require that the thermal, mechanical and cryogenic processes, observed both in the ...

Applications of a gradation equation in coarse-grained soils
Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2019The gradation equation is used to mathematically express the particle size distribution (PSD) of soils. In this paper, a simple and practicable gradation equation and its applications to coarse-grained soils are discussed. First, the proposed equation can be used as an analytical technique for computing particle breakage factors.

Some studies on morphology of the coarse-grained soils
Engineering Geology, 2013Abstract Soil is a particulate material and its engineering properties are mainly controlled by the particle size and shape (i.e., morphological characteristics). In this context, earlier researchers have demonstrated dependence of soil specific parameters like permeability, shear strength, electrical conductivity, thermal conductivity and dielectric

Size Distribution of Coarse-Grained Soil by Sedimaging
Journal of Geotechnical and Geoenvironmental Engineering, 2014AbstractAn 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.

The Freezing Characteristic Curve of a Coarse-Grained Volcanic Soil
2021Volcanic soils are widely distributed in the Hokkaido prefecture of Japan, where seasonal freezing and thawing occur. In frozen soils, a portion of pore water remains unfrozen, due to the effects of capillarity, adsorption, and possibly solute. The variation of the amount of unfrozen water in a frozen soil, which is primarily influenced by subzero ...

A Dynamic Method for Determining the Soil Water Characteristic Curve for Coarse-Grained Soils
Geotechnical Testing Journal, 2000Abstract The air-entry suction is an extremely important parameter in the water characteristic curve, but is difficult to identify when using conventional static methods such as the pressure plate apparatus. In the dynamic method described herein, instantaneous measurement of matric suction and water content are acquired from a soil ...

Comparison of Theoretical and Laboratory Permeability for Coarse-Grained Soil
2020The permeability of soil is an essential parameter in estimating the quantity of seepage under foundation of hydraulic structures, which in turn affect the stability of structures. Empirical correlations such as Hazen, Kozeny–Carman, Breyer, Slitcher, Terzaghi, USBR, Alyamani and Sen are function of grain sizes, porosity/void ratio, coefficient of ...

Latent Heat of Frozen Saline Coarse‐Grained Soil
Journal of Geotechnical Engineering, 1985In 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...

Deformation characteristics of coarse-grained soil with various gradations
Journal of Central South University, 2014By using large scale triaxial shearing apparatus, consolidated-drained shear tests were conducted on coarse-grained soil with different gradations. In order to describe their deformation rules, three main characteristics of tangent Poisson ratio curves were summarized and the reason was revealed by dividing the movement of soil particles into two kinds:
