摘　　要：桶形基础是一种新型海工结构,其应用范围越来越广泛。为满足大港油田滩海油气有效开发需要,在试采平台结构方案研究中采用桶形基础,以使井组既可以进行试采,也可以进行固定生产。基于对试采平台桶形基础抗压承载力、抗滑稳定性、抗倾覆稳定性计算,论证了该基础的安全可靠性,说明试采平台采用桶形基础结构是安全可行的。Bucket foundation is a new type of offshore structure,its application range becomes more and more extensive.In order to satisfy the effective development of Dagang beach oilfields,the bucket foundation scheme was adopted in the research of trial production platform structure,enabling the well group to conduct trial production or fixed production.Based on the calculations of the compressive bearing capacity,anti-sliding stability and anti-overturning stability of the bucket foundation of the trial production platform,the safety and reliability of the foundation were demonstrated.It is shown that the bucket foundation of the trial production platform is safe and feasible.

关 键 词：桶形结构 抗压承载力 抗滑稳定性 抗倾覆稳定性
