Abstract
In Nepal, Many gabion retaining walls for road were damaged after 2015 Nepal Gorkha earthquake. In this study, a full-scale model experiment was conducted to estimate an earthquake behavior and a residual deformation of an erect triple layer placing gabion retaining wall which is 3m high as typical gabion structures seen there. A full-scale model was constructed by packing round stone materials into gabions and filling Masado soil behind the retaining wall in a large soil container. After construction, 4 times shaking tests were conducted and, an expansion of collapsed back fill due to dynamic behavior of the retaining wall was confirmed. According to the measurements of residual deformations, a large inclination of the retaining wall and horizontal displacement of about 80cm at the crest are confirmed. As a result, it was found that the gabion retaining wall is relatively flexible, but it doesn't lead to catastrophic destruction.
