多筒吸力平台沉放调平模型试验

The model tests for adjustment of penetration of multi-bucket foundation platform

描述了位于渤海辽东湾93地区人工岛靠船系缆平台沉放调平模型的试验过程,系缆平台的基础采用了三筒结构型式,这也是我国应用于海洋工程的第一个多筒型基础平台,尽管海上施工前对筒型基础沉放已有了一定的经验, 但多数都是基于吸力锚或单筒式吸力平台结构,对于多筒式吸力基础平台还没有任何的工程经验。试验为海上原型结构沉放施工可行性及施工调平程序的编制起到了一定的指导作用。

A series of model tests have been described for the adjustment of penetration of three-bucket foundation platform that is to be located in the JZ-93 island area, Bohai Sea, China. This also was the first time in the country to use the multi-bucket foundation to the platform. Though many suction anchors have been installed before, there is no experience in installation of the multi-bucket foundation platform. As the result, the model tests have certain effects to guide the construction procedure and feasibility of full-scale structure.
