摘　　要：针对外海深水条件下码头结构面临的浪大流急的恶劣环境挑战,结合常规桩基与重力式码头结构的优点,采用重力式沉箱与桩基相结合的新型复合结构,可有效节约施工工期,减少工程费用。通过与试算工程传统结构的比较,确定和优化了复合结构断面设计和参数。借鉴重力式结构计算模式,考虑复合结构的材料性能、几何参数和设计荷载等随机变量,用JC法计算新型复合结构的抗滑、抗倾可靠指标,结果表明该复合结构是合理的。In response to the challenging environmental conditions of large waves and strong currents faced by dock structures under deep-sea conditions,combining the advantages of conventional mature pile foundation and gravity-type dock structures,the use of a new composite structure combining a gravity-type caisson and pile foundation can effectively save construction time and reduce project costs.The cross section design and parameters of the composite structure are determined and optimized by comparing with the traditional structure of the trial project.With reference to the calculation model of gravity-type structures,considering random variables such as material properties,geometric parameters,and design loads of the composite structure,the reliability index of new composite structure against sliding and tilting is calculated using the JC method,and the results show that the composite structure is reasonable.
