Abstract
Laboratory model tests were conducted to assess the behavior characteristics of geogrid reinforced earth walls using fiber-mixed soil backfill with different surcharge loads and reinforcement spacing. The models were built in the box having dimensions, 100cm tall, 140cm long, and 100cm wide. The reinforcements used were geonet(tensile strength, 0.79t/m) and geogrid(tensile strength, 2.26t/m). Decomposed granite soil(ML) with or without polypropylene fiber was used backfill material. Strain gauges and LVDTs were installed on the retaining walls to measure the strain of the reinforcements and the displacements of the wall facings.
단섬유를 혼합한 토사를 뒤채움재료로 사용한 보강토옹벽의 재하하중 단계 및 보강재 포설단수 별 거동특성을 평가하기 위하여 일련의 축소모형실험을 수행하였다. 높이
