“…In the left-part of this relationship, there is a linear ratio between interface strength and normalized roughness until a critical roughness value is reached. At this point, the shear plane is transferred from the interface to the adjacent soil and a constant coefficient of friction state is established (Brumund and Leonards, 1973;Kishida, 1986a, 1986b;Uesugi et al, 1988;Paikowsky et al, 1995;Dejong and Frost, 2002;Porcino et al, 2003;Dietz and Lings, 2006;Mortara et al, 2007;DeJong and Westgate, 2009;Chen et al, 2015;Di Donna et al, 2015;Feligha et al, 2016). For a sand-concrete interface, Uesugi et al (1990) observed that the critical roughness point occurred around 10% of the mean particle diameter, resulting in an interface friction angle larger than 95% of the sand friction angle.…”

“…Over recent decades, extensive efforts have been made to achieve a complete understanding of soil-solid interface behavior and strength (e.g., Potyondy, 1961;Oumarou and Evgin, 2005;Chen et al, 2015). The literature has currently reached a consensus regarding the key factors that have a major effect on the interface, which include soil properties (e.g., Tiwari and Al-Adhadh, 2014;Canakci et al, 2016;Feligha et al, 2016), particle characteristics (e.g., Kishida, 1986a, 1986b;DeJong and Westgate, 2009), confinement conditions (e.g., Reddy et al, Sastry, 2000;Dietz and Lings, 2006), surface structural characteristics (e.g., Brumund and Leonards, 1973;Paikowsky et al, 1995;Taha and Fall, 2013), soil moisture content (e.g., Miller and Hamid, 2006;Hamid and Miller, 2009;Hossain and Yin, 2014;Borana et al, 2016) and temperature (e.g., Liu et al, 2014;Yavari et al, 2016).…”

“…evaluated the effect of surface roughness on the red clayconcrete interface shear behavior; they noticed that shear dilation is likely to occur on rougher interfaces under lower confining pressure. For a steel-cohesive soil interface, such as high plasticity clay or silt,Feligha et al (2016) noticed three different failure modes as function of the surface roughness: full sliding at the interface; shear failure (or deformation) within the soil; and (3) a mixed behavior. Nevertheless, more comprehensive studies are necessary to achieve the understanding of the interface response between plastic soils and solid surfaces.…”

“…Their results indicated that the soil-interface shearing resistance depends primarily on the surface roughness, water content of soil, and magnitude of the applied stress. The influence of soil water content, surface roughness and normal stress on the relationship between shear stress versus horizontal displacement was investigated by Shakir and Zhu [17] using simple shear apparatus. In their study, different concrete surface roughness's (smooth and rough) were used.…”

Soilstructure interaction is an important theme observed in many civil engineering structures like fondations. The interface shear strength plays a significant role in the analysis and design of many structures constructed above or under the ground. In this study, a total of 28 specimens were tested at vertical stresses of 100, 200, and 400 kPa using direct shear apparatus under consolidated drained condition. A silty sand soil, as per USCS classification system was prepared in the laboratory at different water contents (4.5%, 8.8%, and 12.5%) and voids ratios (0.4, 0.6, 0.8, and 1). The frictional resistance of this soil was measured. The soil samples were also sheared against three steel surfaces of different textures (smooth, moderate-rough, and rough). The experimental results showed that the steel surface texture is an effective factor in soil-steel interface shear strength. The interface shear strength of the rough steel surface was found higher than smooth and semi-rough steel surfaces. In addition to the surface roughness, the water content and void ratio also play important roles in interface shear strength.
