多角度船舶撞击力作用下柔性桩簇的受力分析

Force analysis of berthing pile cluster under action of ship impact from multiple angles

客运码头、老旧码头改造等工程项目广泛利用柔性靠船桩簇来解决其靠船问题,而规范规定将船舶撞击力沿法向作用于柔性靠船桩簇的计算方式却不能满足该结构桩身的最大位移要求。探讨在多角度船舶撞击力作用下柔性桩簇结构中桩身的内力与变形性状,建议在设计过程中,在70°~80°的船舶撞击角度范围内计算结构中桩的最大位移及内力以满足该结构的使用要求,为该结构的设计计算、安全使用及可靠性评估提供参考。

The flexible pile clusters are widely used in the renovation engineering of the passenger wharf and old wharves to solve the problem of ship berthing, but the stipulations in the code concerning the ship impact can＇t satisfy the requirement of the pile＇s maximum displacement. This paper discusses the pile internal force and deformation of the berthing pile cluster structure under the action of ship impact forces from multiple angles, and suggests to calculate the maximal displacement of piles and internal force within the ship impact force angle within the scope of 70~ - 80~ during the design process to meet the operation requirements of the structure and to provide some valuable reference for the structural design and calculation, safe use and reliability evaluation for the berthing pile cluster structure.
