桩靴是钻井平台的重要支撑构件，其结构强度对整个钻井平台的安全起着至关重要的作用。以某自升式钻井平台桩靴为研究对象，根据ABS（美国船级社）规范要求，建立桩靴结构强度的力学模型，并合理简化，分析了预压载和自存两种工况下的设计载荷。利用有限元软件MSC. Patran/Nastran对两种工况下桩靴的强度进行分析，研究得到桩靴强度工程化分析流程以及结构强度特性，分析结果为自升式钻井平台的桩靴设计提供参考。
樁靴是鑽井平檯的重要支撐構件，其結構彊度對整箇鑽井平檯的安全起著至關重要的作用。以某自升式鑽井平檯樁靴為研究對象，根據ABS（美國船級社）規範要求，建立樁靴結構彊度的力學模型，併閤理簡化，分析瞭預壓載和自存兩種工況下的設計載荷。利用有限元軟件MSC. Patran/Nastran對兩種工況下樁靴的彊度進行分析，研究得到樁靴彊度工程化分析流程以及結構彊度特性，分析結果為自升式鑽井平檯的樁靴設計提供參攷。

Spudcan is an important supporting structure for drilling platforms as its structural strength plays a vital role in the safety of the whole drilling platform. Taking the spudcan of a jack-up drilling platform as the research object, this study establishes a spudcan structural strength model according to the ABS (American Bureau of Shipping) regulations with some proper simplification, and analyzes the design load under pre-ballasting and self-survival conditions. After the finite element software MSC. Patran/Nastran is used for the spudcan strength analysis under the two conditions, the engineering spudcan strength analysis procedure and structural strength characteristics are obtained. The analysis results are provided as reference for jack-up drilling platform spudcan design.
