| 摘 要： | 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下桩基础，桶形基础的负压沉贯过程是一个复杂的水动力过程，其关键在于主动脉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流流场进行动态模拟，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一的

| Abstract: | The offshore platform with bucket foundations is a new type of offshore platform that is
different from traditional template platforms by replacing driven piles with bucket foundations
The suction penetration of bucket foundation is a complicated hydrodynamic process The key
of this process is the seepage field caused by the difference of pressure applied on purpose
inside and outside the bucket, The appearance and development of seepage field has a
decisive influence on the suciton penetration process In this study, the finite element analysis
method is utilized to the dynamic simulation of the seepage field of suction penetration of
bucket foundation platform A model of finite element analysis is suggested to solve this
seepage field The reliability of the model and its applicability to engineering have been
proved by comparison between the results of model test and finite element calculation model |
