湖区游艇码头联系桥结构探讨及设计优化

Discussion and Optimum Design of Gangway Structure of Lakeside Yacht Marina

以游艇码头联系桥为讨论对象,分别探讨不同材质的强度特点、适宜尺度以及应用于联系桥的优缺点。其中玻璃纤维复核材料、碳纤维复核材料联系桥长度一般为2~3 m,木材联系桥长度一般为3~6 m,铝合金联系桥长度一般为10~24 m,钢联系桥长度可大于30 m,但其不能很好满足游艇码头的美观需求,后期维护较麻烦,且需考虑支撑端的特殊设计。同时本文针对湖区特点提出一种联系桥的优化结构方案,能够有效解决若干工程难点,以便为类似设计提供参考。

Marina’s gangway is taken as an example to explore the strength,suitable sizes,merits and demerits of different materials applied to the gangway.The lengths of the gangway are generally 2~3 m for glass fibre composites and carbon fibre composites,3~6 m for timber,10~24 m for aluminum.Steel gangway may be more than 30 m long,but cannot meet aesthetic requirements for marinas.In addition,it is hard to maintain and requires special design in supporting end.An optimized structural solution is also proposed in view of the characteristics of lake district,which can effectively solve several engineering difficulties.The research results will provide a reference for similar design.
