水泥混凝土桥面铺装结构防水层设计在港珠澳大桥中的应用

Application of Waterproof Concrete Layer Design of Cement Concrete Bridge Deck Pavement in Hong Kong-Zhuhai-Macao Bridge

针对港珠澳大桥所面临的湿热等特殊环境条件,对其水泥混凝土桥面结构防水层进行了特殊设计,论文通过对比分析现行桥面铺装防水层设计现状,结合防水材料及防水结构的试验分析,建立了沥青混合料+防水黏结层+水泥混凝土基面的桥面铺装防水结构体系,并对铺装层防水结构的施工工艺进行了介绍。

In view of the special environmental conditions of Hong Kong Zhuhai Macao Bridge, such as humidity and heat, the waterproof layer of cement concrete bridge deck structure is designed. Based on the comparative analysis of the current design status of the waterproof layer of the bridge deck pavement, combined with the test analysis of waterproof materials and waterproof structure, the paper establishes the waterproof structure system of the bridge deck pavement with asphalt mixture + waterproof adhesive layer + cement concrete base, and introduces the construction technology of the waterproof structure of the pavement.
