Abstract
This study evaluated the stability and deformation subsea foundation after implementation of the contaminant isolation method by covering the contaminated materials using Zeolite and sands under subsea condition. The appropriate contaminant adsorption materials used in this study was selected as Zeolite based on the existing research results due to its efficiency. Safety (or stability) was evaluated by calculation and to analyze deformation after completing the contaminant isolation method. The minimum safety factors from slope stability analyses results were 30.1 and 11.2 depending on subsea submerged conditions and the amount of the maximum primary consolidation settlement from consolidation analysis results was 209.2 mm. In addition, change of consolidation amount with increasing consolidation time was evaluated based on consolidation degree.
