钢结构桥梁防腐施工技术

Anti-corrosion Construction Technology of Steel Structure Bridge

随着国家基础设施建设的快速发展,钢结构设计逐步朝着跨度大、强度高、自重轻、设计经济等方向发展,使桥梁工程的建设迎来了崭新的局面。钢结构桥梁的结构腐蚀、应力腐蚀、疲劳是使钢结构桥梁寿命降低的重要原因之一。以钢结构桥梁建设为例,结合工程实际对钢结构桥梁防腐施工技术及钢结构防腐的重要性进行了阐述。

With the rapid development of national infrastructure,steel structure design has gradually moved to the direction of large span,high strength,light weight,and design economy,which has ushered in a new situation for social bridge construction.However,structural corrosion,stress corrosion and fatigue of steel bridge are the important causes for reducing the life of steel bridge.Taking steel structure bridge as an example,the importance of anti-corrosion construction technology of steel structure bridge and steel structure anti-corrosion is analyzed in combination with engineering practice.
