Abstract

In this study, the dynamic compaction method was selected by analyzing field situation, soil condition data and compaction test characteristics of the special selected soils, and the compaction method for using the selected soils as the site restoration soil of the ○○ city non-sanitary landfill maintenance project. The N value in the standard penetration test (SPT) before and after dynamic compaction increased by an average of 89% over the range 12∼18, and the allowable bearing capacity of the plate bearing test (PBT) was ranged 150∼227 kN/m2, at least 80% higher than that before test. As a result, it can be seen that the same tendency as the dynamic compaction effect applied to the existing dredging and waste landfill is shown.

본 연구에서는 ○○시 비위생매립장 정비사업 시행시 발생하는 특수한 선별토사를 부지 복원토로 활용하기 위한 다짐방안으로 현장상황과 선별토사의 토질조사 자료, 다짐시험 특성을 분석하여 동다짐공법을 적용하였다. 동다짐 전･후에 수행한 표준관입시험(SPT)에서 N치는 12∼18 범위로 동다짐 전보다 평균 89% 증가하였으며, 평판재하시험 (PBT)의 허용지지력은 150∼227kN/m2 범위로 다짐 전에 비해 최소 80%이상 증가하였다. 이러한 결과로 기존의 준설 및 폐기물 매립지에 적용된 동다짐 효과와 비슷한 경향을 나타내고 있음을 알 수 있었다.
