本文根据AP1000施工现场的腐蚀现象，对典型的钢结构、焊缝和设备等腐蚀现象进行了总结，基于腐蚀的表现形式，分析了引起施工现场材料和设备腐蚀的主要原因，并对腐蚀现象的形成机理进行了分析，从理论和施工实践的角度给出了预防性措施。%On the basis of corrosion phenomena appeared on the AP1000 construction site, this article summarized the typical corrosion phenomena on the steel structure, weld joints and equipments. The main causes that lead to materials and equipments corrosion on site have been analysed based on the corrosion patterns, so as the formation mechanism of the corrosion. Anti-corrosion measures have also been proposed from theoretical and construction practical point of view.
