Effect of Non Plastic Silt on the Anisotropic Behavior of Sand

Effect of Silt Content on the Anisotropic Behaviour of Silt-Sand Mixtures

“…For that the soil becomes softer. This behaviour has been described by Yoshimine and Ishihara (1998) for Toyoura sand and by Bahadori and Ghalandarzadeh (2008) for a Firoozkuh sand-silt mixture [4]- [32]. It seems regardless of type of sand, similar behaviour can be observed in all studied cases here.…”

“…Among recent relevant studies, Bahadori and Ghalandarzade (2008) studied the inherent anisotropic effects on the undrained behaviour of sands using HCTS [4]- [10]. In this research, the anisotropic behaviour of Tehran sand with different silt contents in 400 kPa initial effective confining stress are studied.…”

Specimen Preparation Methods for Artificially Cemented Sand in Simple Shear and Hollow Cylinder Apparatuses

“…This silica sand, which is classi ed as SP in the USCS, is a commercial arti cially crushed sand with sub-angular to angular grains and is completely well-known and documented in the academic research of Iran (e.g., [20][21][22][23][24][25][26][27][28][29]). Physical properties of the base soil are presented in Table 1 and the grain size distribution curve is shown in Figure 1.…”

“…Such studies mostly focus on the rotation of principal stresses ( parameter) and intermediate principal stress parameter (b) (e.g. Vaid et al [17], Yoshimine et al [18], Yang et al [19], Bahadori et al [20], Kumruzzaman and Yin [21], Sivathayalan et al [22], Baziar and Shara [23], Baziar et al [24], Jafarian et al [25], and Keyhani and Haeri [26]). Considering that the studies on cemented sands have mostly been limited to triaxial and direct shear devices, evaluation of the arti cially cemented sand behavior in more sophisticated apparatuses, such as HCA, capable of simulating anisotropy in a wide range of values would be signi cant as it demonstrates the e ect of added cement on the anisotropic mechanical behavior of the base soil.…”

Propiedades geotécnicas de los estériles mineros de la mina de Riotinto, Huelva-España

“…El estudio confirmó que los finos tienden a debilitar los especímenes de suelo y que en las muestras reconstituidas, el efecto de los finos puede ser exagerado según el tipo de prueba que se realice. De igual manera, Bahadori et al (2008) señalan que la adición de diferentes cantidades de limo no plástico a la arena, causa una respuesta dramática de ablandamiento, incluso a elevadas densidades, y que las arenas limosas presentan una tendencia elevada a fluir comparada con una arena pura. Dash et al (2010) realizaron ensayos triaxiales monotónicos y cíclicos, a fin de evaluar la influencia de finos no plásticos en la respuesta de una arena limosa bajo carga cíclica.…”
