摘　　要：桶形基础采用负压沉贯法施工 ,与压桩、打桩等施工方法显著不同 ,且阻力特性受地基性质影响很大。介绍了一组粉土地基条件下的模型试验情况 ,探索了桶形基础的沉贯阻力与负压、渗流等的关系 ,并与实际平台沉贯过程进行了对比。The bucket foundation suction penetration technique is different from the pile driving technique, and the characteristics of penetration resistance is greatly influenced by the seabed character. The model tests for a set of silty seabed are introduced, the relations of the penetration resistance to the negative pressure and seepage flow are explored, and the comparison between the test results and the actual penetration results is also made.
