索结构在桥梁工程中的应用及基本防腐处理措施

Application of Cable Structure in Bridge and Basic Antiseptic Measures

研究目的:索结构在桥梁工程中得到了日益广泛的应用,其主要应用桥型范围是悬索桥、斜拉桥、拱桥、系杆拱桥等,索的构造也相应分为缆索、拉索及吊索等多种类型,根据桥梁索结构所处的环境条件,相应对其提出了很高的防腐性能要求。研究结论:索结构由于其优异的材料性能特点,在桥梁等多种工程中得到广泛应用,为保证长期安全使用,对索结构的防腐应采取综合工程措施。目前对构成索结构的材料采取的基本防腐处理措施主要为热浸镀锌和环氧喷涂处理。

Research purposes： The cable structures are widely used in bridge day by day and their main applicable areas include cable suspension bridge, cable - stayed bridge, arched bridge, tie - arch bridge and so on. The cable structures are correspondingly divided into many kinds of type, such as cable, guy cable, hanging cable and etc. According to the environmental condition in the place where the bridge with cable structure locates, very high antieorrosion performance of the bridge with cable structure is required. Research conclusions：As the materials for cable structure have good performances, the cable structure is widely used in bridge. For ensuring the service safety of the bridge for long term, the antiseptic measures should be taken to the cable structure. At present, the basic antiseptic measures for cable structure materials are mostly galvanizing by hot - dipping and epoxy spray coating.
