摘要
主要对公路旧桥加固方法中的体外预应力加固法进行介绍,并通过工程实例对体外预应力加固法在旧桥加固中的效果进行了验证,检测数据表明,体外预应力加固法能够较好地改善结构整体受力状况,提高旧桥的承载能力,因此,可以说体外预应力加固法是一种有效的旧桥加固方法。
Mainly introduce external prestressing strengthening method of highway old bridge reinforcement method,verify the effect of external prestressing strengthening method on the old bridge reinforcement by engineering examples,the test data indicates that external prestressing strengthening method can well improve structure overall stress condition,and enhancing carrying capacity of old bridge,hence,it can be said that external prestressing strengthening method is an effective old bridge reinforcement method.
