Abstract
본 연구에서는 연약지반이나 부분침하의 복원에 사용되는 팽창약액의 강도특성을 정량적으로 평가하기 위하여 팽창성능을 구분한 팽창약액을 제작하여 강도특성을 조건에 따라 분석하였다. 상대적 고팽창군과 저팽창군으로 구분하여 실험을 실시하였으며, 각각 최대 팽창부피에 대해 10~30%의 부피를 제어한 공시체를 제작하여 강도 평가를 수행한 결과 시간에 따라 강도가 증진되는 것을 확인하였고, 고팽창군과 저팽창군의 압축강도는 약 2.1배의 차이를 보였다. In this study, to quantitatively evaluate the strength characteristics of the inflatable liquid used for the recovery of soft ground or partial settlement, the inflatable liquids were prepared by dividing the inflatable capacity and the strength characteristics were analyzed according to the conditions. The experimental group was divided into two groups: relatively high expansion group and low expansion group. The specimens were prepared by controlling the volume of 10 ~ 30% of the maximum expansion volume, and the strength of the specimens were evaluated. The compressive strength of the high expansion group and low expansion group was about 2.1 times.
