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 ...

Undrained Fragility of Clean Sands, Silty Sands, and Sandy Silts

Journal of Geotechnical and Geoenvironmental Engineering, 2002
In this paper, intergranular (\Ie\dc\N) and interfine (\Ie\df\N) void ratios and confining stress are used as indices to characterize the stress-strain response of gap-graded granular mixes. It was found that at the same global void ratio (\ie) and confining stress, the collapse potential (fragility) of silty sand increases with an increase in fines ...

Suffusion compressibility of cemented silty sands

Soil Mechanics and Foundation Engineering, 1991
The All-Union Scientific Research Institute of Foundations and Underground Structures has investigated the mechanical properties of cemented silty sands. The soils for the tests were taken from the sites at the Tengizsk oil-gas deposit.

Liquefaction potential of reinforced silty sands

2015
In this study a series of cyclic triaxial tests were performed to examine the undrained dynamic resistance of silty sand reinforced with various arrangements of geotextile layers. The silt content of samples varies in percentage from 0, 10, 20, 30, 40 and 50%.

Stabilization of Silty Sand with Nontraditional Additives

Transportation Research Record: Journal of the Transportation Research Board, 2002
A laboratory experiment was conducted to evaluate the stabilization of a silty- sand (SM) material with nontraditional chemical or liquid stabilizers. SM soil specimens were mixed with various stabilization products and compacted using a gyratory compaction machine to approximate ASTM D1557 moisture—density compaction.

Isotropic yielding of unsaturated cemented silty sand

Canadian Geotechnical Journal, 2013
Unsaturated cemented soils are frequent both as designed materials and as naturally occurring layers. Both desiccation and cementation act separately as hardening mechanisms, but it is not clear how exactly their effects combine. Do they enhance one another? Are they mutually reinforcing? This study presents results from an experimental campaign aimed

Shear Strength and Stiffness of Silty Sand

Journal of Geotechnical and Geoenvironmental Engineering, 2000
The properties of clean sands pertaining to shear strength and stiffness have been studied extensively. However, natural sands generally contain significant amounts of silt and/or clay. The mechanical response of such soils is different from that of clean sands.

Using Paper as Reinforcement in Silty Sand

Advanced Materials Research, 2012
Reinforced soil has been among the most effective soil modification materials. Its use has been expanded rapidly into civil engineering, geotechnical engineering and pavement engineering. Reinforcing subgarde in pavement systems has always been an issue.

A Case Study on Silty Sand Liquefaction

2016
Silty sand liquefaction has been of great interest of research in geotechnical earthquake engineering. This article presents preliminary results of a case study on nonplastic silty sand liquefaction. Influence factors such as fines contents and disturbance effects on dynamic properties of silty sand are carefully discussed in this paper.
