Shear creep behaviour of soil–structure interfaces under thermal cyclic loading

Géotechnique Letters, 2023
The coupling effect of initial shear stress and thermal cycles on the thermomechanical behaviour of clay concrete and sand–concrete interfaces has been studied. A set of drained monotonic direct shear tests was conducted at the soil–concrete interface level.

Basic features of soil structure interface behaviour

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1989
Abstract Firstly experimental data of friction along piles in sand are presented; the corresponding element test (direct shear test between a granular soil and a rough construction material) is described, showing the effect of the initial conditions and of the prescribed path.

A Model for the Behaviour of Soil-Structure Interface

1998
The study of the mechanical behaviour of the soil-structure interfaces in the context of the theoretical framework of strain localization is presented in this paper. Classical conditions for localization of deformation are compared with other existing criteria and applied, by means of deviatoric hardening constitutive model, to the analysis of the ...

Flow behaviour and piping potential at the soil–structure interface

Géotechnique, 2019
The piping phenomenon that occurs at a soil–structure interface, referred to as backward erosion piping, is often observed beneath hydraulic structures such as conduits buried in levees. In this study, the flow behaviour and piping characteristics at the soil–structure interface were investigated by theoretical analysis using ideal uniform spherical ...

Enhancement of a hypoplastic model for granular soil–structure interface behaviour

Acta Geotechnica, 2016
Modelling of interfaces in geotechnical engineering is an important issue. Interfaces between structural elements (e.g., anchors, piles, tunnel linings) and soils are widely used in geotechnical engineering. The objective of this article is to propose an enhanced hypoplastic interface model that incorporates the in-plane stresses at the interface.

Behaviour of interfacial layer along granular soil-structure interfaces

Structural Engineering and Mechanics, 2003
As shear occurs along a soil-structure interface, a localized zone with a thickness of several grain diameters will develop in soil along the interface, forming an interfacial layer. In this paper, the behaviour of a soil-structure interface is studied numerically by modelling the plane shear of a granular layer bounded by rigid plates.
