Özet
This paper investigates the dynamic performance of suction bucket foundations supporting wind turbines in fully and partially saturated soils, a topic that has received limited attention in geotechnical research. Numerical analyses using PLAXIS2D were conducted to study the effects of relative density and degree of saturation on the dynamic behavior of suction bucket foundations installed in loose to dense sandy soils under fully and partially saturated conditions. The models were subjected to strong ground motion and cyclic wind loads, with responses such as excess pore pressure ratio, settlement, rotation, and spectral acceleration of the suction bucket foundation evaluated. The results demonstrate that partial saturation significantly reduces the settlement and rotation of suction bucket foundations compared to fully saturated sands, particularly in dense soils. However, partially saturated soils also transfer higher accelerations to the structure. These findings suggest that partial saturation can be a viable liquefaction mitigation technique for wind turbines, offering improved performance without disrupting turbine operation.
