Effect of soil conditioning on the permeability of coarse-grained soil in mechanized tunnelling [PDF]
In coarse-grained soils, the reduction of soil permeability via conditioning can effectively prevent groundwater from entering the chamber, thus providing better tunnel face control and ultimately preventing excessive settlements of the surface. In this study, several mixtures of coarse-grained and soil-foam mixtures were utilized in experiments.

Applicability of UH model to coarse-grained soil [PDF]
Large-scale triaxial, K0 compression and constant stress ratio path tests were carried out on two kinds of coarse-grained soils. Stress-strain relationships of these tests were simulated by using UH model for sands to study the applicability of the model to different stress paths of coarse-grained soil, and the results were compared with those of ...

The dilatancy deformation and particle breakage effects of coarse-grained soil have a significant influence on the safety and stability of high earth and rock-fill dams. To study the shear deformation and particle breakage characteristics of coarse-grained soil, four groups of soil sample with different coarse grain contents were to conduct ...

Study of coarse-grained soils design characteristics
Abstract The article presents the results of deformation characteristic studies for soils containing various amounts of rock clastic material during its use as a working layer of the subgrade and the foundations of pavements. The studies were performed on coarse soil models using the geotechnical software package Plaxis, which avoided ...

Effect of Gradation on the Compactability of Coarse-Grained Soils
The optimal gradation for coarse-grained soil used in earth-rockfill dams is an essential design index when determining the compactability of coarse-grained soil. With the optimal gradation, coarse-grained soil can be rolled to the maximum of dry densities among all gradations under the same compaction effort.
