摘要

The development of offshore wind power must rely on reliable offshore engineering platforms. Since the offshore environment is unpredictable and the on-site working conditions are very complex and harsh, it requires humans to have a deeper understanding of the marine environmental conditions, and to design methods and construction techniques for offshore engineering buildings. There must be a greater improvement in order to reduce the project cost, shorten the construction period, reduce the follow-up maintenance and have a longer service life under the premise of ensuring safety and reliability. Therefore, based on the existing engineering technology, there is still a great research prospect to propose a more safe, efficient construction and relatively low cost offshore foundation form. This paper discusses the theoretical research and experimental research of the traditional offshore wind turbine pile foundation and the new pile-bucket combined foundation. The results show that the new pile-bucket combined foundation enhances the horizontal bearing capacity of the single-pile foundation and compensates for the suction bucket foundation in shallow soil. The defect that it is difficult to exert the carrying capacity in soft soil areas.
