Abstract

Reinforced soil retaining wall is a typical infrastructure that secures structural stability from the earth pressure of background as well as economic efficiency by a simple construction method. Researchers and engineers have reported damage cases due to stress concentration to the convex, known as the weakness of reinforced soil retaining wall hitherto. Various reinforcing construction methods such as applying reinforcing materials in layers are used. However, studies on the failure mechanism from stress concentration at the curved part of the reinforced soil retaining wall are scarce. In this study, the curved part of the reinforced soil retaining wall is modelled using three-dimensional numerical analysis and the behaviour of the retaining wall according to the angle is analysed. Three angles are considered, i.e. 45, 90, 135°, and the influence of overburden load are compared in each case. The authors quantitatively analysed and compared the horizontal displacement and the settlement between a curved and straight portion of the backfill surface of the wall.
