为了治理桥梁的病害,提高桥梁的安全性和使用寿命,以桥梁工程、工程力学、交通工程学等理论为基础,围绕混凝土桥梁具体结构特点,从分析桥梁的重要性入手,通过对桥梁加固的发展现状研究,采取对比法对桥梁加固方法进行对比分析,提出了适合于混凝土桥梁加固的技术方法和加固计算,并用等效矩形应力图形代替曲线应力图形使计算简化,为中小型混凝土桥梁的加固提出了一种简便的方法。
In order to control the disease of the bridge and improve the safety and service life of the bridge, based on the theory of bridge engineering, engineering mechanics, traffic engineering and so on, based on the concrete structure characteristics of the concrete bridge, starting from the analysis of the importance of the bridge, The research on the current situation of the bridge reinforcement is carried out by comparing with the method of strengthening the bridge. The technical method and reinforcement calculation suitable for the reinforcement of the concrete bridge are put forward, and the calculation is simplified by replacing the curve stress graph with the equivalent rectangle stress graph. Proposed a simple method.
