摘要
介绍了海上平台桶形基础模型（模型桶）压力压贯和负压沉贯的试验概况，对比分析了两者贯入力的巨大差异和产生的原因，给出了模型桶压力压贯中贯入深度与压力的关系，负压沉贯中负压与贯入深度、抽吸泵流量、基土渗流量、桶内土塞隆起之间的关系。试验结果表明，负压沉贯可以大大降低以砂质粉土为基土的土抗力，为在胜利油田类似基土海域海上平台应用桶形基础提供了试验依据，为海上现场导管架桶形基础平台的安装就位施工和控制提供了经验。
In this paper, survey of model experiment of press penetration and suction penetration of bucket foundation is introduced comparison and analysis of the big difference and the reasons of penetration force caused by the two method are explained; the relation between penetration depth and press force in the press penetration method and the relations among suction and penetration depth, the rate of flow in pump, the rate of flow in original soil, the soil height in the bucket are given The result shows that suction penetration can greatly reduce the resistance caused by original soils, and evidence for using bucket foundation on the bottom in the sea area of 'SHENGLI OIL FLELD' is presented with as the same as the original soil, and gives experience for fixing and controlling jacket bucket foundation platform is stated
