Design of piles for a berthing structure on artificial slope

In present study, a new berthing structure is proposed for slope stable dredging activity. A slope with a weak soil structure comprising gravel, sand–silt clay, stiff silty clay, and terra firma at various depths is stabilized with ground improvement techniques. The pile makes dredging difficult for a single-slope angle. To overcome this difficulty, different slopes are recommended for different depths. This study analyses the slope stability for such a design by finite element modeling. Modeling shows that the factor of safety is> 1.5 for the varied slope structure, thus proving that the design is effective in preserving the slope stable.
