Measurement of Stiffness Anisotropy in Kaolinite Using Bender Element Tests in A Floating Wall Consolidometer

Engineering Behavior and Characteristics of Water-Soluble Polymers: Implication on Soil Remediation and Enhanced Oil Recovery

“…Recently, organic agents such as polymers, biopolymers, and surfactants have been developed for soil improvement and have demonstrated their abilities to improve the shear strength, stiffness, soil remediation, and erosion resistance of geomaterials [1][2][3][4][5][6][7][8][9]. Furthermore, biopolymers, such as polyacrylamide (PAM) and xanthan gum, have shown a great effect in enhanced oil recovery (EOR)…”

Advanced application of seismic cone penetration test at complex ground conditions

“…The stress model parameters α and β are site-specific material constants that can be experimentally determined using the V S -σ c ′ plot. In prior studies, inverse trends between the parameter α and β were reported (Cha et al, 2014;Kang et al, 2014;Ku et al, 2011;Santamarina et al, 2001). At various SRS locations, this stress-dependency model was examined based on the noted in-situ V S profiles below ground water table (e.g., 15 to 45 m depths).…”

Effects of organic matter on stiffness of overconsolidated state and anisotropy of engineered organoclays at small strain

“…Additionally, natural soils are often anisotropic because the in-situ stress condition is generally anisotropic or because soil fabric has directivity during deposition (Mitchell and Soga 2005;Roesler 1979;Santamarina et al 2001). A number of studies have been performed to evaluate the stiffness anisotropy of inorganic soils (Kang et al 2014;Wongsaroj et al 2007;Yimsiri and Soga 2011).However, few studies,have looked at the effects of preloading and anisotropy on the dynamic behaviors of organic soils.…”
