从钢筋腐蚀及混凝土碳化裂化入手分析影响钢筋混凝土桥梁耐久性的因素,介绍了现行公路桥梁规范控制耐久性的规定,以及提高混凝土桥梁耐久性的新方法,以引起桥梁工作者对桥梁耐久性的重视。最后提出钢筋混凝土桥梁耐久性问题原因通常是由设计和施工的失误引起的,只要控制好各种指标,耐久性问题就解决了。 This paper analyzes the factors that affect the durability of reinforced concrete bridges from the corrosion of steel bars and the carbonization cracking of concrete. It also introduces the requirements of the current highway bridges to control the durability of concrete and the new method to improve the durability of concrete bridges to induce bridge workers’ durability to the bridges Pay attention. Finally, the reasons for the durability of reinforced concrete bridges are usually caused by mistakes in design and construction. As long as various indicators are controlled, the durability problem is solved.
