摘要
描述了位于渤海辽东湾93地区人工岛靠船系缆平台原型顶升的试验过程,系缆平台的基础采用三筒结构型式,这也是我国应用于海洋工程的第一座多筒型基础平台。尽管海上施工对筒型基础沉/拔过程有了一定的经验,但筒型基础平台在长期使用后的拔出复用还没有任何的工程经验,此次顶升试验验证了筒型基础平台移动复用的可行性,利用主要测试结果给出了筒基上拔顶升力的相关分析,对海上原型结构顶升施工的可行性及筒型基础使用过程中的动态抗拔力的变化具有直接的参考意义。
Two moot dolphin platforms with bucket foundations were installed in JZ9-3 field of the Bohai Sea in 1999.This also was the first time in China to use the multi-bucket foundation to the platform.Though bucket foundation platform has been installed before,there is no experience in pulling up process of the multi-bucket foundation platform after long time use.The reutilization of buckets is proved in the pulling up test.According to the results,the analysis about the pulling up forces is given;and the results have certain effects to guide the construction procedure and the further study about pulling up forces.
