摘要
由于特种车辆需要通行某石拱桥,需对该桥进行了检测评定和结构验算,提出了增大截面的加固设计方案,再以加固后的拱桥为对象,利用有限元软件对加固后的结构进行建模分析。通过结构计算、现场检查和荷载试验等工作,评价了该桥加固后的承载能力和使用性能,为该桥在特种车辆安全通行提供了保障。对于今后同类桥梁的加固设计及评价具有一定的参考价值。
As a result of the special vehicle passing through, carried on the inspection and the appraisal to a stone arch bridge, and put forward the reinforcement design plan of enlarging the section. Then the reinforced arch bridges as the object, modeling and analysis of reinforced structure by finite element software, through the structure calculation, onsite inspection and loading reinforced bridge, provided a guarantee during reinforcement design and evaluation of similar test, evaluated the bearing capacity and using performance of the the special vehicle operations. It has certain reference value for the bridges in the future.
