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:

Inadequacy in the Classification of Coarse-Grained Soils
Geotechnical Testing Journal, 1990Abstract This note explores the rationale behind the unified soil classification system for coarse-grained soils. A few deficiencies in the system are pointed out. A density function plot of the grain-size distribution is proposed to supplement the grain-size distribution curve, which the author believes will minimize the ambiguities and

Water-vapor-heat behavior in a freezing unsaturated coarse-grained soil with a closed top
Cold Regions Science and Technology, 2018A series of one-side freezing experiments with closed tops were performed to illustrate moisture migration and frost heave mechanisms of the coarse-grained soil for high speed railway subgrades in cold regions, as well as silty clay and standard sand as ...

Modeling SWCC for Coarse-Grained and Fine-Grained Soil
2020Following Chap. 2, the work is extended to predict SWCC of a soil with different initial densities by using Bayesian method, for both coarse-grained and fine-grained soil. An adjustment parameter (β) is introduced to express the relationships between the matric suctions of two soil samples.

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
