摘　　要：目前国内有大批桥梁因承载能力下降需要进行加固处理,针对现有纷繁复杂的桥梁维修加固方法,结合工程实例,选用两种常规的桥梁加固方法,采用有限元软件对桥梁加固前后的受力性能变化进行分析比较,并对经济性进行比较,结论可为桥梁设计者、管理者等选用桥梁加固方法提供一定的理论依据。Due to the decroasing of bridges bearing capacity, a large number of bridges need to be strengthened. In view of vary of bridge maintenance method, two kinds of conventional bridge reinforcement methods for bridge engineering project are selected. The bearing capacity of the bridge before and after the strengthening is analyzed by finite element software . With comparing economy of the bridge, some conclusions can provide certain theoretical basis for bridge designers and managers to selecting the bridge strengthening method.
