Experimental Study on the application of reinforced retaining walls to the railroad
보강토 옹벽의 철도 구조물 적용에 관한 실험적 연구
Abstract
This research reviews the characteristics of earth pressure incurred by GRS-RW mainly used in the railroad design in order to resist large lateral load caused by train and additional load induced by facilities such as noise barrier fences, electric poles, etc. The results of test shows the existence of arching effect that horizontal earth pressure increases in the backfill while earth pressure applying to the wall reduced under GRS-RW system. In both cases, unreinforced wall and GRS-RW system, the coefficient of earth pressure (K) is about 0.4 at the rest. However, after lateral displacement occurs, the earth pressure nearly reduce down to zero under GRS-RW system while the earth pressure decreases up to 0.12 in case of unreinforced retaining wall.
