    摘要
  • 吸力筒基础作为一种高效、经济、环境友好的基础形式，在海洋工程特别是海上风电领域得到了广泛的应用，多以吸力筒导管架形式出现。如何实现吸力筒安全、高效沉贯，并满足吸力筒导管架安装技术指标是施工设计的关键。本文系统总结了吸力筒基础在粘土和砂土地层中沉贯阻力、需求吸力和容许吸力计算方法。结合具体施工案例开展沉贯分析，预测了吸力筒的自重贯入深度，掌握了合理的吸力设置方法及容许吸力主要限制因素，为海上吸力筒导管架基础施工提供技术参考。
    As an efficient， economical and environmentally friendly foundation form， suction bucket foundation has been widely used in marine engineering. Among them， the jacket foundation supported by multiple suction bucket is widely used in the offshore wind power field. How to realize the safe and efficient penetration of the suction bucket and meet the technical indicators of the installation of the suction bucket jacket is the key to the construction design. This paper systematically summarizes the calculation methods of penetration resistance， required suction and allowable suction of suction bucket foundation in clay and sand layers. Based on specific construction cases， the penetration analysis is carried out， the self-weight penetration depth of suction bucket is predicted， and the reasonable suction setting method and the main limiting factors of allowable suction are mastered， which provides technical reference for offshore construction of suction bucket jacket foundation.
