초록

최근 토공사 품질관리를 위한 지능형 다짐 기술이 토공사 품질관리 기준으로 주목받고 있다. 본 연구에서는 지능형 다짐기술과 이를 활용한 토공사 품질관리 기준을 분석하고, 현장시험을 통해 지능형 다짐기술을 활용한 토공사 품질관리 시험시공 절차에 대해 고찰하였다. 실트질 모래(SM) 성토재의 현장다짐시험을 통해 다짐 횟수가 증가할수록 CMV와 기존의 다짐품질 시험결과 값이 증가하는 상관성을 확인하였다. 시험시공 데이터를 토대로 평균 CMV 및 품질관리 목표 CMV 도출을 하였다. 평판재하시험 지지력계수와 상관성 통해 목표 CMV(34.2)와 CMV 증가율 분석방법을 통해 목표 CMV(36.6)를 산정하였다. 본 논문을 통해 지능형 다짐기술을 이용한 현장 다짐 품질관리 절차 및 방법론에 대하여 논의하였으며, 아울러 해당 기술의 국내 적용 가능성을 고취시키기 위한 지능형 다짐 품질관리 방안을 제언하였다.

Recently, the intelligent compaction technology for quality control of earthworks has brought attention as a quality control standard for earthworks. In this study, intelligent compaction technology and earthwork quality control methods were investigated and earthwork quality control procedures using intelligent compaction technology were considered based on field tests. Through the field compaction test of the silty sand (SM) fill material, it was confirmed that CMV and bearing capcaity index from plate load tests increased as the number of compactions increased. Based on the field test data, the average CMV and quality control target CMV were derived. The target CMV (34.2) was calculated through the correlation with the bearing capacity index of the plate load test, and the target CMV (36.6) was calculated through the analysis of the CMV increase rate. In this paper, the on-site compaction quality management procedure and methodology using intelligent compaction technology were discussed, and an intelligent compaction quality management method was proposed to promote the applicability of the technology.
