摘要
目前钢筋混凝土梁桥抗弯加固的方法主要包括加大截面、改变结构体系、粘钢加固、焊接补筋、体外预应力加固和纤维增强复合材料加固等,这些方法有着各自的适用条件和结构类型。结合工程实践综合比较这些方法,对工程建设具有一定的参考价值。
There are many methods of strengthening concrete bridge against bending at present,such as increasing cross-section, changing the structural system, bonding steel, welding up bar and strengthening with external prestressing or fiber reinforced composites etc. These methods have their selves conditions and structure type. Comparing these methods with engineering practice has some reference value to engineering construction
