摘要
不同于道路建设,钢筋混凝土桥梁由于施工材料自身的特性,很容易产生裂缝,而雨水和空气中的二氧化碳会通过裂缝渗入结构内部腐蚀钢筋,使钢筋的强度降低,从而影响桥梁结构的承载力,对桥梁的使用安全造成影响,因此,需要加强钢筋混凝土桥梁防腐蚀设计分析。论文以钢筋混凝土桥梁的防腐施工为核心展开讨论,概述腐蚀钢筋混凝土桥梁的环境,分析导致钢筋混凝土桥梁发生腐蚀的因素,提出钢筋混凝土桥梁防腐蚀性能提升策略。
Different from road construction,reinforced concrete bridge is easy to crack due to the characteristics of construction materials.The carbon dioxide in the rain and air will penetrate into the structure through cracks to corrode the steel bar,so that the strength of the steel bar is reduced,thus affecting the bearing capacity of the bridge structure and the use of the bridge safety.Therefore,it is necessary to strengthen the anti-corrosion design analysis of reinforced concrete bridges.This paper takes the anti-corrosion construction of reinforced concrete bridge as the core to discuss,outlines the environment of corroded reinforced concrete bridge,analyzes the factors leading to the corrosion of reinforced concrete bridge,and puts forward the strategy to improve the anti-corrosion performance of reinforced concrete bridge.
