摘　　要：在建的以色列阿什杜德港项目的 Q28码头为全直桩的高桩梁板式码头,采用重力式沉箱作为后方陆域吹填的挡土墙结构,并利用抛石形成护岸。针对其结构复杂、施工组织难度大的特点,通过施工期的波浪场数值模拟及物理模型试验,对该码头的设计思路进行分析。结果表明,当主防波堤延伸段施工尚未对施工区域形成整体掩护时,重力式沉箱结构可以对后方的陆域吹填及板桩码头施工提供一定程度掩护,桩间抛石护岸则可以有效地减少直立式沉箱壁的波浪反射作用。同时,根据施工实际情况对设计断面提出优化建议,确保项目的顺利实施。Quay 28 of Hadarom port under construction is all vertical standing pile structure with beam and slab.In addition,we apply caissons as the retaining wall for the reclamation area in the rear,and dump rocks between steel pipe piles to form revetment.Aiming at the great construction difficulty of this complex structure,we use numerical modeling of wave field and physical model test to analyze the design purpose of this complex structure.As a consequence,the caissons can provide shield for the reclamation and sheet pile construction in the back before the main breakwater extension is completed.The rocks are dumped between steel pipe piles,which can reduce the wave reflection by caissons.Meanwhile,some cross sectional design optimizations are purposed according to the actual implement situation to guarantee the construction progress successfully.
