Modeling the fiber addition influence on the small strain shear modulus of sand
(Springer, 2017-07)
The mechanical behavior of fiber reinforced soils has been extensively studied in the last decades. Previous studies have shown that inclusion of fibers increases the shear strength of the reinforced soil. However, the ...
Characterizing a tropical soil via seismic in situ tests
(2019-01-01)
The shear wave velocity (Vs) is an important geotechnical parameter to be used in dynamic problems (e.g. earthquakes and vibration problems) as well as in static deformation analysis such as excavations and foundation ...
Retrieving shallow shear-wave velocity profiles from 2D seismic-reflection data with severely aliased surface waves
(Elsevier Science, 2019-02)
The inversion of surface-wave phase-velocity dispersion curves provides a reliable method to derive near-surface shear-wave velocity profiles. In this work, we invert phase-velocity dispersion curves estimated from 2D ...
Site characterization at Chilean strong-motion stations: Comparison of downhole and microtremor shear-wave velocity methods
(Elsevier, 2015)
A blind comparison of independent invasive (downhole, standard penetration, bender element) and noninvasive microtremor shear-wave velocity (Vs) profiling is presented for 11 strong-motion stations in central and southern ...
Experimental study of the complex reflection coefficient of shear waves from the solid-liquid interface
(2010-01-01)
The determination of the reflection coefficient of shear waves reflected from a solid-liquid interface is an important method in order to study the viscoelastic properties of liquids at high frequency. The reflection ...
Possible ionospheric preconditioning by shear flow leading to equatorial spread F
(European Geosciences Union (EGU), 2005-10-14)
Vertical shear in the zonal plasma drift speed is apparent in incoherent and coherent scatter radar observations of the bottomside F region ionosphere made at Jicamarca from about 1600–2200 LT. The relative importance of ...
Roll wave prediction model of Herschel–Bulkley fluids evolving on porous bottom
(2021-09-01)
The media have been reporting natural disasters frequently associated with climate change. When it comes to mudflows, the impact is substantial, especially on highly vulnerable communities. Under appropriate conditions ...
