A Succinct Review on Soil Structure Interface Thickness
https://orcid.org/0000-0002-8857-9509
Abstract Interface is an intermediate element occurs at soil-structure junction. The interface should be modeled in such a way that the proper values of settlement and horizontal displacement can be obtained. During shearing, a thin layer of soil is formed due to slipping and rolling of particles just near the structure due to its roughness. The layer is called as thin layer interface. Hence consideration of thin layer interface is essential for realistic behavior of soil structure interaction (SSI) system. As per the Finite Element Method (FEM) formulation, as thickness increases the tangential displacement also increases, thus choice of appropriate thickness is necessary otherwise it will result in inappropriate distribution of forces in SSI system. The formation of thin shear zone and its thickness depend on many parameters such as particle size, normal stress, soil type, interface internal friction angle, roughness of surface, adhesion etc. Hence the prevailing criterion based only on particle size, doesn’t seem sufficient for every soil and site conditions. Also the available criteria are derived for cohesion less soil only. Hence an attempt has been made in this paper to review and represent the appropriate consideration of thickness for thin layer interface in SSI modeling along with its advantages and limitations.
