Abstract: As an efficient， economical and environmentally friendly foundation form， suction bucket foundation has been widely used in marine engineering. Among them， the jacket foundation supported by multiple suction bucket is widely used in the offshore wind power field. How to realize the safe and efficient penetration of the suction bucket and meet the technical indicators of the installation of the suction bucket jacket is the key to the construction design. This paper systematically summarizes the calculation methods of penetration resistance， required suction and allowable suction of suction bucket foundation in clay and sand layers. Based on specific construction cases， the penetration analysis is carried out， the self-weight penetration depth of suction bucket is predicted， and the reasonable suction setting method and the main limiting factors of allowable suction are mastered， which provides technical reference for offshore construction of suction bucket jacket foundation.
