| 본 연구에서 미관통과 관통 샌드컴팩션파일(SCP) 개량지반에 대하여 일차원 압밀거동을 조사하기 위하여 실내모형실험을 실시하였다. 모델점토지반에 간극수압계, 토압계, 다이얼게이지등을 설치하여 SCP 개량지반의 압밀침하량과 응력분담비등을 측정하였다. 실험 결과, 미관통 SCP 지반의 압밀침하량은 관통 SCP 지반의 압밀침하량 보다 더 크게, 응력분담비는 더 적게 나타났다. 또한 SCP 개량지반의 응력분담비는 압밀시간, 지반심도, 상대밀도, 치환율과 관통률에 따라 변화됨을 알 수 있었다. |

| A series of model tests was conducted to investigate the one-dimensional consolidation behavior of an improved ground where sand compaction piles(SCP) were either fully or partly installed in the model clay ground. In order to check the one-dimensional consolidation settlement and stress concentration ratios, earth pressure, pore pressure transducers and dial gauges were installed in the model clay ground. The test results revealed that the consolidation settlement of the partly penetrated SCP ground was larger than that of the fully penetrated SCP ground, and the stress concentration ratios (m) of the fully penetrated SCP ground were higher than these of the partly penetrated SCP ground. The stress concentration ratio was decreasing with the increase in the penetration depth of SCP |
