港珠澳大桥西人工岛结合部非通航孔桥是实现桥隧转换和西人工岛相接的桥梁,桥面设计高程低,上部结构需承受波浪荷载、主梁变宽、设计限制条件多、耐久性等问题突出。以风浪荷载和耐久性问题为出发点,介绍了本桥在抗风浪设计、支座选用、不锈钢钢筋采用、防腐和抗冲磨涂装方案、混凝土耐久性措施等方面的创新设计。 Hong Kong-Zhuhai-Macao Bridge West artificial island combination of non-navigable bridge is to achieve the conversion of bridge tunnel and the West artificial island phase of the bridge, the bridge design elevation is low, the superstructure to withstand wave loads, the main beam widening, design constraints and more durability Other issues stand out. Based on the problems of wind and wave load and durability, this paper introduces the innovative design of this bridge in terms of wind-resistant wave design, bearing selection, stainless steel reinforcement, anti-corrosion and anti-abrasion coating solutions and concrete durability measures.
