盘锦某应急泊位工程码头结构设计要点

Key structural design points for an emergency berth engineering wharf in Panjin

针对盘锦某小型应急泊位工程码头结构设计问题,考虑工程所在区域自然条件及码头设计船型的特点,根据国内规范和以往工程经验,确定适合本工程的码头结构形式和桩基形式,并总结在潮差较大、船型多样、地震惯性力大、冰情严重区域的小型码头结构设计要点。结果表明,高桩梁板式码头结构对水深较浅的砂质地质有更好的适应性,设置多处叉桩的钢管桩桩基结构能够满足码头承载力和抗震抗冰的要求,双层系缆平台能够兼顾水位差较大情况下不同船型的安全系泊,下层系缆平台预制走道板迎冰面采用棱角形结构可有效抵抗冰荷载。

In view of the structural design of a small emergency berth engineering wharf in Panjin,we consider the natural conditions of the area where the project is located and the characteristics of the design ship types for the wharf,and determine the wharf structure and pile foundation suitable for the project according to the domestic codes and previous engineering experience.We also summarize the key structural design points for small wharves in areas with large tidal ranges,various ship types,large seismic inertia forces,and severe ice conditions.The results show that the high-piled beam-slab wharf has better adaptability to shallow sandy geology.The steel pipe pile foundation with multiple fork piles can meet the requirements of wharves for load-bearing capacity and seismic and ice resistance.The double-layer mooring platform is equipped for the safe mooring of different types of ships in the case of large water level differences.The ice load can be effectively withstood by an angular shape on the ice-facing surface of the prefabricated walkway slab of the lower mooring platform.
