뒷채움재 및 그리드 종류에 따른 인발특성 = Characteristics of Pull-out According to Grid and Backfill

다국어 초록 (Multilingual Abstract)

In this study, the applications of the recycled aggregate as a backfill of reinforced has been estimated and experimented for the pull-out of backfill-reinforced material. After the large model box was made, pull-out test was performed installing strain gage at the reinforced grid and surcharged by pressurized air bag. Backfill was made by recycled aggregate and soil, estimated frictional efficiency was estimated according to 2 types of reinforced grid. From the results, the maximum tensile strength was 14~17% higher when backfill is recycled aggregate. Frictional strength was not changed according to grid. However, frictional strength was higher when backfill is recycled aggregate.
