摘　　要：洋山深水港工程依托外海岛礁地形通过填海造地形成港区,其关键技术之一就是采用何种码头及接岸结构型式才能阻挡软土地基上平均23～26 m高回填土的作用。文章重点介绍一期工程码头及接岸结构在复杂的自然条件、较高的使用要求、恶劣的施工条件以及较短施工周期等条件下,按照有利于工程快速施工、有利于陆域形成以及有利于控制质量的原则,提出采用高桩码头结构+斜顶桩板桩承台驳岸结构型式。实施效果表明:该结构型式适合洋山港区的地质条件和建设条件,有利于港区的陆域形成及后续工程的推进,技术风险小;后方高回填土对码头结构没有影响。Yangshan Deepwater Port is built in the reclaimed land with the backing of offshore islands and reefs. One of the key technologies for the construction of Yangshan Deepwater Port is to select which type of structure for the wharfs and the shore connection to resist the action of the backfill of averagely 23m - 26m high on the soft soil foundation. The paper focuses on the piled wharfs and batter piles with sheet-pile supported platform bulkhead structure proposed for the first phase of Yangshan Deepwater Port with the consideration of the complex natural conditions, high operational requirements, severe construction conditions and short working period and on the principle that the proposed type of structure should be beneficial to the rapid execution of the works, formation of the land and quality control. The implementation of the project showed that the type of structure selected for the project was suitable for the geological and construction conditions in the Yangshan port area and beneficial to the formation of the land area of the port and the continuation of the follow-up projects. With little technical risks, the thick fill in the rear area posed no threat to the wharf structure.
