Experimental study on the determination of small strain-shear modulus of loess soil

HBRC Journal, 2016
The primary aim of this study was to investigate the collapse potential of loess soil in Egypt, the factors affecting the dynamic properties of this soil and establish relationships between them. Whether engineered or natural, may exist in seismic zones;

The influence of suction changes on the stiffness of railway formation

, 2011
Despite compacted soils being unsaturated, geotechnical design is predominantly based on saturated soils,despite it being known that differences exist between the behaviour of saturated and unsaturated soils.Suction in soils has been shown to increase ...

Comparison of small-strain shear modulus and Young’s modulus of dry sand measured by resonant column and bender–extender element

, 2019
The small-strain shear modulus and Young’s modulus of dry sand are simultaneously measured by resonant column and bender–extender element tests. Two different methods are adopted to calibrate the resonant column and the results indicate that the ...

Measurements of Shear Wave Velocity for Collapsible Soil

Geotechnics
This paper examines the effects of collapsible soil structure on shear wave velocity. The study attempts to simulate hydraulic fill sand deposits, which represent a natural soil deposition process that can result in a collapsible soil structure. A series

Innovative Triaxial/Resonant Column Equipment

, 2010
The present paper describes a new triaxial apparatus which allows the measurement of low strain stiffness by means of both bender elements and resonant column test. In a previous paper Squeglia et al.

Laboratory Investigation on Shear Modulus and Damping Properties of Port Soft Clay Improved by Dynamic Compaction

Applied Sciences
Dynamic compaction has been widely applied to reinforce soft soils in port areas due to its high efficiency and cost-effectiveness. However, a comprehensive understanding of the deformation mechanisms and stiffness evolution of treated soils under static

A modified linear-elastic model for calibration of resonant column devices accommodating drive system compliance [PDF]

Measurements of small-strain shear modulus of soils and rocks using the resonant column apparatus are highly dependent on accurate physical characterisation of the apparatus's drive components.

Generation of 10-m-lengthscale plasma columns by resonant and off-resonant laser pulses

, 2023
Creating extended, highly homogeneous plasma columns like that required by plasma wakefield accelerators can be a challenge. We study the propagation of ultra-short, TW power ionizing laser pulses in a 10-meter-long rubidium vapor and the plasma columns ...
