DESIGN OF REDUCED DIAMETER MOMOPILE FOUNDATION FOR OFFSHORE WIND TUEBINE UNDER SOFT GROUND CONDITIONS
Based on the real design parameters and environmental load,PLAXIS Monopile Designer and SACS software were used to realize the optimal design of reduced monopile in a wind field of China.The ultimate strength,structural deformation,natural vibration frequency and fatigue analysis were carried out.The reduced monopile with the same upper size had a larger mud surface angle and horizontal displacement,and a lower vertical displacement and natural vibration frequency.The results verify the feasibility of the reduced monopile scheme,and achieve a 10.9%reduction in steel consumption.
