The behavior of a compressible silty fine sand

open access: yesCanadian Geotechnical Journal, 1999
Publications associated with sands are often limited to clean (i.e., little fines content), uniform, uncemented silica or quartz sand. On the other hand, the importance of mineral content, particle shapes, as well as gradation to the behavior of sand has long been recognized.

Comparative studies on mechanical behavior of frozen natural saline silty sand and frozen desalted silty sand

Cold Regions Science and Technology, 2016
Abstract To compare the mechanical behavior of natural frozen saline silty sand before and after a desalting process, the collected natural frozen saline silty sand with/without desalting is reconstituted to soil samples with water content at 13%. Triaxial compressive tests are carried out under confining pressures ranging from 0.3 to 3 MPa and at ...

Heave of silty sands

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1977
Freezing tests were conducted at the University of Washington Periglacial Laboratories on predominantly quartz mineral silty sands at five different gradations, with a degree of fineness of (grain size diameter less than 0.02 mm) 5.6%, 8.4%, 10.6%, 15.4%, and 21.5% by weight.

Strength and Dilatancy of Silty Sand

Journal of Geotechnical and Geoenvironmental Engineering, 2014
AbstractFines content can have a great influence on the mechanical behavior of sand. The effect of fines content has not been taken into account in most of the strength-dilatancy relationships for sand. An attempt was made in this paper to account for the influence of fines content on the strength-dilatancy relationship of silty sands. The test data on

Dynamic compaction of saturated sands and silty sands: theory

Proceedings of the Institution of Civil Engineers - Ground Improvement, 2009
Dynamic compaction (DC) with pre-installed wick drains is an emerging soil improvement technique for densification and liquefaction mitigation of saturated low-permeability loose sands containing non-plastic silts. The compaction process induces excess pore pressures, possible soil liquefaction, and concurrent densification.

Dynamic compaction of saturated sands and silty sands: design

Proceedings of the Institution of Civil Engineers - Ground Improvement, 2009
Current practice for design, suitability assessment, and determination of the optimum field operation parameters for dynamic compaction rely mainly on field pilot tests, past experience, and empirical equations. At present there are no detailed analytical procedures available to determine the densification achievable, or to analyse the effects of ...
