The Characteristics of Sedimentation-Consolidation and Surface Strength for Dredging and Landfill Areas in Each Coast

Abstract

, 2015ABSTRACT : This study gives the characteristics of sedimentation-consolidation and surface strength for dredging and landfill areas in each coast. For the analysis of the sedimentation-consolidation characteristics, the column tests were performed and the results were compared with existing various literatures and design reports for dredged soil disposal. The surface strength of landfill soils of west and south coast were investigated by using the portable cone tester. As a results of analysis, the coefficient of sedimentation-consolidation on south coastal dredging soils is more sensitive with variation of initial water contents than on the west coastal dredging soils. And the surface strength of the dredging landfills is a higher in the west coast than in the south coast. Finally, the results of this study will be utilized as a basis data for analysis and design in the field of dredging and landfill.Keywords : Sedimentation, Consolidation, Surface strength, Dredging, Landfill, Portable cone penetration test요지 : 본 연구는 국내 해역별 준설토의 침강압밀 특성 및 투기장 내 매립된 준설매립토의 표층강도 특성을 조사하였다 . 준설토의 자중압밀특성 분석을 위하여 Column test를 수행하고 그 결과를 기존의 문헌자료 및 해역별 준설토 투기장 설계 자료와 비교 ・분석하였다. 또한 휴대용 콘 관입시험기를 이용하여 서해 및 남해 연안 주요 매립지에서 현장시험을 수행하고 준설토의 매립 후 표 층강도를 분석하였다. 분석결과 침강압밀계수는 남해안 지역의 준설토가 서해안 준설토 보다 초기 함수비에 대해 좀 더 예민하게 변화하는 것으로 나타났으며, 준설매립지의 표층강도는 서해안이 남해안보다 큰 강도 값을 나타내었다. 이러한 연구결과는 준설매립분야의 해석 및 설계를 위한 중요한 자료로 활용 가능할 것으로 사료된다 .주요어 : 침강, 압밀, 표층강도, 준설, 매립, 휴대용 콘 관입시험
