MODEL LOADING TEST OF ANCHORED GABION REINFORCED SOIL WALL

Abstract

 Anchored gabion reinforced soil wall is considered to be more structurally stable than steel-frame-faced reinforced soil wall. In previous studies, apparent cohesive strengths of earth-retaining structures with horizontal reinforcement as well as soilbags which have similar reinforcement effects as gabions were evaluated. However, the effect of the different type of wall facing has not been fully estimated. A series of multi-stage loading tests were done on earth-retaining structure with anchored gabion-faced structure and steel-frame-faced structure. As a result of the tests, it was confirmed that the anchored gabion-faced structure recorded higher performance to withstand horizontal load exerted by the earth pressure. Moreover, the amount of contribution given by the anchored gabion-faced structure to the apparent cohesive strength was evaluated by Mohr-Coulomb failure criterion. When FEM analysis was conducted, it was concluded that further investigation on analytical parameters are needed to accurately replicate the test results.
