摘　　要：某工程地处开敞式海域复杂地形区,潮流特征复杂、风浪及码头下方水深变化大,为满足复杂建港条件下船舶的安全靠离泊,采用密排导流桩与高桩码头相结合的混合结构,通过潮流、波浪、系泊物理模型试验验证该新型结构的应用效果,确定系、靠泊作业标准。试验结果表明:该结构可有效改善流态、减小横流强度,并通过调整导流桩间距改变导流效果,进而降低工程投资。新型码头结构整体受力可充分发挥各部分功能作用,实现改善码头前沿水域水文条件,达到工程技术和经济的平衡,旨在为类似复杂建港条件下的码头结构设计提供借鉴。A certain project is located in an open sea area with complex terrain,complex tidal characteristics,and large changes in wind,waves,and water depth below the dock.To meet the safety of ship berthing and disembarking under such complex port construction conditions,a hybrid structure combining closely arranged diversion piles and high pile docks is adopted.The application effect of this new structure is verified through physical model tests of tidal currents,waves,and mooring,and the standards for mooring and berthing operations are determined.The experiment shows that this structure can effectively improve the flow state and reduce the cross flow intensity.At the same time,the diversion effect can be changed by adjusting the spacing between the diversion piles,reducing the engineering investment.The overall stress of the new dock structure can fully utilize the functions of each part,improve the hydrological conditions of the dock front water area,and achieve a balance between engineering technology and economy.The aim is to provide reference for the design of dock structures under similar complex port construction conditions.
