Shear modulus of hydrate bearing calcareous sand-fines mixture [PDF]
E3S Web of Conferences, 2019 This article presents a laboratory study on the maximum shear modulus of a THF hydrate bearing calcareous sand (CS)–fines mixture. The maximum shear modulus was inferred from the shear wave velocity measured from the bender elements installed in a ...

Effect of Wave Attenuation on Shear Wave Velocity Determination Using Bender Element Tests
Sensors, 2022 Wave attenuation is a widespread physical phenomenon in most acoustic tests, but there is a scarcity of quantitative investigations into the influence of wave attenuation on the determination of shear wave travel time in bender element tests.

Relating wave frequency and pore fluid homogeneity in quasi-saturated sands [PDF]
E3S Web of Conferences, 2023 P-wave velocity is regularly proposed as a proxy for water saturation when studying quasisaturated soils. However, several authors have underlined that this velocity can only be reliably correlated to water saturation if the pore fluid is “homogeneous ...

Local Stiffness Assessment of Geogrid-Stabilized Unbound Aggregates in a Large-Scale Testbed
Applied Sciences, 2023 This paper integrates and extends an earlier article presented at the 20th International Conference on Soil Mechanics and Geotechnical Engineering. The generation of a stiffened zone in the proximity of a geogrid is one of the primary mechanisms of ...

Dynamic Properties of Calcareous Sands from Urban Areas of Abu Dhabi
Applied Sciences, 2022 Abu Dhabi (ABD) has recently developed its national building code that mandates dynamic analysis of large structures to seismic loadings. Large strain dynamic properties such as shear modulus (G) and damping ratio (D) of local undisturbed calcareous ...

Wavelet analysis of bender element signals [PDF]
Géotechnique, 2012 Accurate determination of shear wave arrival time using bender elements may be severely affected by a combination of near-field effects and reflected waves. These may mask the first arrival of the shear wave, making its detection difficult in the time domain. This paper describes an approach for measuring the shear wave arrival time through analysis of

A note on influence of stress anisotropy on the Poisson's ratio of dry sand
Journal of Rock Mechanics and Geotechnical Engineering, 2017 In this study, extender and bender element tests were conducted investigating the small-strain Poisson's ratio of variable sands, with a focus on the effect of stress anisotropy in order to quantify the sensitivity of Poisson's ratio to the applied ...

Evaluating the maximum shear modulus (G0) for different bender-soil coupling loads [PDF]
E3S Web of Conferences, 2020 The current paper aims to test the effects of vertical loads on the maximum shear modulus (G0). The tests were undertaken with unsaturated soils in unconfined conditions.
