桥梁技术在重件码头设计中的应用

Application of bridge technology in design of heavy cargo wharf

宜昌船舶柴油机厂自用重件码头工程设计特点是将部分桥梁技术转移到重件码头设计上:1)解决伸臂梁承担荷载过大而引起的强度和挠度等系列问题,主梁采用大跨度桥梁设计理念,选用自锚式斜拉伸臂梁设计方案,减轻钢箱梁自重、降低施工难度;2)江中两主墩采用大跨度桥梁桥墩设计理念,采用大直径钻孔灌注群桩基础,来承受主梁传给主墩很大的扭矩和船舶挤靠力。自2009年10月21日起该码头正式投入使用,目前使用状况良好,该码头在结合桥梁技术方面为类似工程设计提供了很好的借鉴作用。

The design feature of Yichang vessel diesel engine plant self-used heavy cargo wharf is to transform part of the bridge technique to the gravity wharf design.One feature is to solve the strength and deflection problems caused by the over load on the suspension beam.The main beam adopts the large-span bridge design concept,choose the self-anchored cable-stayed cantilever beam design plan,reduce the self-weight of the steel box beam,and also reduce the construction difficulty.The other feature is that two main piers in the river adopt the large-span bridge pier design concept,adopt the large-diameter bored cast in-situ pile group foundation to help the main pier bear the torsion and ship breasting force transmitted from the main beam.The design of this wharf may serve as a reference for the relevant project design in combining the bridge technology.
