“…It has been indicated that the irreversible volumetric strain due to dilatancy also gradually increases with increasing number of shear cycles (Figs. [4][5]; this demonstrates that the soil near the structure is continuously compressed due to cyclic shear application. Thus, we conclude that there is a signiˆcant evolution in the physical state, including particle-crushing and compression of the soil near the structure due to shear application.…”

“…Clough and Duncan (1971) presented a model of an interface assuming a hyperbolic tangential stress-displacement relationship under a constant normal stress condition. Desai et al (1985) modiˆed the Romberg-Osgood model to describe the cyclic tangential stress-displacement relationship of an interface. These models are widely used in numerical analysis because of their simplicity, however, they cannot adequately simulate the plastic deformation and volumetric changes of a soil-structure interface.…”

This paper describes an elasto-plasticity damage model, termed the EPDI model, of the interface between a structure and gravelly soil. The formulations are derived on the basis of a new model framework, with test-basis concepts and assumptions, for a uniˆed description of monotonic and cyclic behavior of such an interface. The model parameters, with physical meaning, are easily determined from a group of cyclic shear tests and a conˆning compression test. The comparisons of model predictions with the results for a series of tests under varying loading conditions demonstrate that the EPDI model is eŠective in accurate description of monotonic and cyclic stress-strain relationship of the interface between a structure and gravelly soil with capturing new features, including: 1) shear stress-strain relationship and comprehensive volumetric strain response (e.g., partly dependent on shear strain); 2) volumetric strain response that is dependent on the shear direction; and 3) evolution of behavior of the interface associated with the evolution of physical state.

“…Clough and Duncan [1] proposed the non-linear elastic model Clough-Duncan model for interfaces according to their direct shear tests. Desai [2,3] issued the disturbed state concept based on cyclic tests, which filled the gap in geotechnical engineering in terms of damage mechanics. The elasto-plasticity damage interface model (EPDI) [4] was established on the basis of substantial tests.…”

The Numerical Simulations of Clay-Concrete Interface Tests on the Mesoscopic Level

Abstract. The issue of the interface between soils and structures is an important research area in the high embankment dam. The particle flow code (PFC 3D ) that uses the discrete element method, can be used to research various geotechnical engineering problems, including the interface problems. Numerical simulations by PFC 3D entail the mesoscopic parameters of walls and particles, i.e. the cohesion strength, tensile strength, the wall friction and the interparticle friction that are critical to determine whether the results of the simulations can be consistent with those of tests. On the basis of a large number of numerical simulation tests, this paper tries to reveal the connections between these mesoscopic parameters and macroscopic mechanical properties in the clay-concrete interface tests. Then macroscopic and mesoscopic properties of the interface are analysed by numerical simulations.

“…A number of works have been carried out on the friction characteristics of granular soil-concrete interface with both static and dynamic load conditions for example [2], Who proposed a modified Ramberg-Osgood model was for the modeling of soil-concrete interface behavior [3], demonstrated the presence of a shear band whose thickness, is 5D 50 . Zhang and Zhang [4], developed equipment for conducting static and cyclic shear test.…”
