吸力桶与圆沉箱整体预制式新型离岸深水码头

A new type of entirely prefabricated offshore deep-water wharf composed by suction bucket foundations and circular caissons

为了开发能够更好地适应软土地基和恶劣波浪条件的离岸深水码头,结合吸力桶和圆沉箱的优点,提出了吸力桶与圆沉箱整体预制式新型离岸深水码头。阐述其结构组成、平面布置和施工工艺,分析了其承载特性。该结构靠岸侧可布置泊位、靠海侧可兼做防波堤,抗浪能力强,具有承载性能好、结构刚度大、耐久性好、费用省和对环境影响小的优点,应用前景广泛。相比无隔舱的吸力桶,此新型结构通过设置内圆桶和内隔板,抗滑和抗倾覆能力大幅提高。贯入损伤对基础安装就位时的承载力有比较明显的降低作用,建议在设计中考虑。

In order to develop an offshore deep-water wharf that can better adapt to soft foundation and severe wave conditions, a new type of entirely prefabricated offshore deep-water wharf with suction bucket foundations and circular caissons is proposed by combining the advantages of suction bucket foundations and circular caissons. Its structural composition, plane layout and construction technology are expounded, and its bearing characteristics are analyzed. The structure can be arranged with berths on the shore side, and can also be used as a breakwater on the sea side. It has strong wave resistance, good bearing performance, high structural rigidity, good durability, low cost and little impact on the environment, and has wide application prospects. Compared with the suction bucket without compartment, this new structure greatly improves the anti-slip and anti-overturning ability by setting the inner bucket and clapboards. Penetration damage can significantly reduce the bearing capacity of the foundation when it is in place, and it is recommended to consider it in the design.
