Modelling performance of a sloped reinforced soil wall using creep function

The paper describes a rheological model based on a series of Kelvin models for analysing creep behaviour. This model is implemented in a finite element analysis to predict the behaviour of an instrumented sloped reinforced soil wall. The performance of the numerical model and the actual behaviour of the structure are compared. The analysis is carried out using both constant and variable reinforcement stiffness with respect to time. The results and the findings are discussed.
