摘　　要：针对T型梁桥承载能力不足、裂缝宽度过宽病害存在很多种加固方式,而采用增大T梁截面,并在扩大尺寸内部布设普通钢筋的加固方法,进而提出一套成熟的施工工艺,实践证明该种加固方式可以在同类桥梁加固、维护工程中推广应用。There are many kinds of reinforcement means towards the weak bearing capacity of T beam bridge and the big crack width. The reinforcement method of increasing T beam section and adding common steel bar in the widened part is adopted and one set of construction technique is put forward. This method is proved to be worth popularization and application in the similar engineering.
