摘要
从箱形拱桥的桥型结构特点入手,分析了钢筋混凝土箱形拱桥主拱圈开裂、拱上建筑破损等典型病害现象,结合工程实例,介绍了几种常用的箱形拱桥的加固与改造措施,为拱桥的加固与改造提供参考。
Starting from the structural features of a box arch bridge, the diseases of RC box arch bridge are analyzed here, such as the arch cracks and the structural damages of constructions on the arch. According to actual engineering conditions, many strengthening measures of the arch bridge are introduced, thus providing some references for reinforcing engineering of the arch bridge.
