Dynamic compaction of saturated sands and silty sands: results

Proceedings of the Institution of Civil Engineers - Ground Improvement, 2009
Numerical simulations of dynamic compaction of three loose saturated sands and silty sand sites are presented. The theory associated with the numerical model is presented in a companion paper. First, a case history of dynamic compaction in a clean sand site without pre-installed wick drains is considered.

Cyclic undrained behavior of silty sand

Soil Dynamics and Earthquake Engineering, 1995
Abstract Laboratory cyclic triaxial tests were performed to investigate the effect of fine content on the pore pressure generation in sand. Strain-controlled, consolidated undrained tests have been performed with a cyclic shear strain range of 0·015-1·5%.

Liquefaction Testing of Stratified Silty Sands

Journal of Geotechnical and Geoenvironmental Engineering, 2000
The cyclic behavior of stratified silty sandy soils is at present poorly understood, yet these materials are commonly found in alluvial deposits and hydraulic fill, which have a history of liquefaction during earthquakes. The main objective of this research project was to compare the behavior of stratified and homogeneous silty sands during seismic ...

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.

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.

Liquefaction Screening—Non-plastic Silty Sands and Sands

2018
Liquefaction screening of sands and silty sands using cone penetration resistance is a difficult problem. The presence of silt particles among the sand grains in non-plastic silty soils alter the intergrain contact density and affect cyclic resistance, flow and consolidation characteristics, and cone resistance of the soil.

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.

Mitigation of Liquefaction Potential of Silty Sands

From Research to Practice in Geotechnical Engineering, 2008
Mitigation of liquefaction potential of soils with fines contents greater than 15 to 20 percent usually requires special adaptation of the dynamic densification methods — Deep Dynamic Compaction, Explosive Compaction, Vibro-Compaction, Compaction Piles — that are ordinarily used to improve loose, clean cohesionless soils.

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.
