Lessons Learned from Failure of Geogrid-Reinforced Segmental Retaining Wall
블록식 보강토 옹벽의 하자발생 사례 분석
Abstract
The numbers of geogrid-reinforced walls are widely used in Korea. This papers present the results of two failure case histories of geogrid-reinforced segmental retaining walls. The geological background of the construction sites, detailed construction sequences, and the amount of rainfall were examined. The failure of these reinforced walls are caused by the improper drainage system and foundation treatment, too sharpened curvature of corner work, and too high height of wall.
