摘要

桶式基础在海洋工程中具有广阔应用前景，其安装可行性分析的核心是沉贯阻力计算。通过理论推导建立了基于土体强度指标和静力触探贯入阻力的两类桶式基础沉贯阻力计算方法之间的联系。对黏土，侧壁沉贯阻力系数可按黏聚力因子与锥尖阻力系数的比值确定；端部沉贯阻力系数可按条形地基承载力系数与锥尖阻力系数的比值确定。对砂土，侧壁沉贯阻力系数与侧压力系数和界面摩擦系数成正比，与基础形状系数和地基承载力超载压力系数成反比；端部沉贯阻力系数为形状系数的倒数。基于北海地质条件确定的沉贯阻力理论值与经验值相近，为沉贯阻力系数提供了理论基础。并针对我国海床地质条件，开展沉贯阻力系数研究。

Abstract

Bucket foundation has promising application prospects in offshore engineering. The calculation of penetration resistance is essential to such foundation installation feasibility analysis. The relationship between the calculation methods of penetration resistance of bucket foundation based on soil strength index and cone penetration resistance is established through theoretical derivation. For clay

the side wall penetration resistance coefficient can be determined by the ratio of cohesion factor to resistance coefficient of cone tip; and the tip penetration resistance coefficient can be determined by the ratio of strip foundation bearing capacity coefficient to resistance coefficient of cone tip. For sand

the side wall penetration resistance coefficient is in proportion to the lateral pressure coefficient and interface friction coefficient

and in inverse proportion to the foundation shape factor and surcharge bearing capacity factor; and the tip penetration resistance coefficient is the reciprocal of the foundation shape factor. The theoretical values of penetration resistance coefficient determined by the geological conditions of the North Sea are close to the empirical values

which provides a theoretical basis for the penetration resistance coefficient. According to the geological conditions of seabed in China

the penetration resistance coefficient is also studied.
