桶形基础平台是一种新型的海洋平台，这种型式的平台与传统的导管架式平台的主要区别在于采用桶形基础代替打入桩基础，桶形基础的负压沉贯过程是一个复杂的水动力过程，其关键在于主动施加的桶内外压力差产生渗流场，渗流场的形成与发展对于负压沉贯有决定性的影响。本文用有限元分析方法对桶形基础负压沉贯渗流场进行动态模拟，建立了桶形基础负压沉贯过程中渗流场的有限元分析模型，模型试验的结果与按有限元分析计算模型得到的计算结果的比较表明了计算模型的可靠性和工程实用性。
The barrel-shaped basic platform is a new type of offshore platform. The main difference between this type of platform and the traditional jacket-type platform is the use of a bucket-shaped foundation instead of a driven pile foundation. The negative pressure penetration process of the bucket-shaped foundation is a complex process. The key to the hydrodynamic process lies in the active application of pressure difference between the inside and outside of the barrel to generate a seepage field. The formation and development of the seepage field has a decisive influence on the negative pressure penetration. In this paper, the finite element analysis method is used to simulate the penstock seepage flow field of the bucket foundation negatively, and the finite element analysis model of the seepage field of the bucket foundation negative pressure penetrating process is established. The results of the model test are calculated by the finite element analysis model. The comparison of the calculated results shows the reliability of the calculation model and the engineering applicability.
