摘要
该文通过对目前上海市桥梁病害的检查,对引起预应力桥梁内预应力钢筋锈蚀的产生原因作出分析。接着有针对性地提出改进孔道压浆材料的方案,并使之与普通压浆材料进行施工比对,从中找出解决预应力钢筋锈蚀的方法。
According to the inspection of bridge fault in Shanghai,the article analyzes the rust cause of prestressed steel bar in the prestressed bridge beam,then puts forward the scheme to improve the pathway grouting material,and compares it with the common grouting material in the construction to find the method to solve the prestressed steel bar rust.
