摘　　要：扎瓦尔项目是工程量巨大的综合性港口开发项目,涉及码头、航道疏浚、防波堤、护岸、陆域形成和基础处理等各类工程。由于海域表层土质较硬,疏浚工程难度很大。扎瓦尔一至四期建设大规模采用衡重式小方块码头结构,减少了大型水工施工设备投入;对防波堤和护岸结构的护面块体进行优化,保证了施工质量和结构安全;采用无围堰回填技术和200 m3液压抓斗船的创新型疏浚工艺,使大型挖泥船连续施工得以顺利实施;结合业主的使用要求和绞吸船的吹距,对总平面布局进行优化,在提高码头运营便利性的同时,加快了工程进度。本文总结的设计和施工工艺优化成果可为类似海外水运工程建设提供参考。The Zawr project is a comprehensive port development project with a huge volume of works, involving various types of works such as quay wall, channel dredging, breakwater, shore protection, land formation, and soil improvement. The dredging project is very difficult due to the hard surface soil of the sea. Zawar phase Ⅰ to phase IV construction adopts the equilibrium-weigh small cube quay structure, which reduces the input of large hydraulic construction equipment. The armor block of revetment and breakwater is optimized, which guarantees the quality and safety of the marine structure. The innovative dredging technology adopting no-cofferdam backfilling technology and the 200 m3 hydraulic grab ship enable the continuous construction of large dredgers. The optimization of the general layout in line with the owner’s usage requirements and the blowing range of the cutter-suction dredger improve the convenience of terminal operation while speeding up the project schedule. The design and construction technology optimization results can provide a reference for similar overseas water transportation projects.
