Abstract

The reinforced soil retaining wall is one of the civil structures that people who living in the city can come into closely such as foundation, slope, road, etc. Studies on reinforced soil retaining wall method have been carried out variously according to the development of back-fill or reinforcement materials, and there are multiple design standards to ensure structural stability. However, most of them have limitations that have not considered curved part of reinforced soil retaining walls, which is the weakest point of wall, as under two-dimensional plane-strain conditions. In this study, therefore, the convex part of the reinforced soil retaining wall was modeled via three-dimensional numerical analysis and the behaviour characteristics corresponding to the curvature of the curved part of the one was compared with the straight part and analyzed. As a result, the horizontal displacement and settlement for convex part greater occurred than straight and the closer straight to curved part, the reduction of deviatoric stress are increased.
