| 摘 要： | 由于桥梁在运营期间会受到气候、氧化、腐蚀或老化等因素影响,以及长期在恒载和活载的作用下遭受损坏,其强度和刚度会随时间的推移而降低,采用断裂力学及损伤力学的方法就桁式组合拱桥长期使用性能问题进行探索,并结合实例分析,对桁式组合拱桥养护具有积极意义。

| Abstract: | The bridge is influenced by climate,oxidation and aging during operation,moreover,it is damaged under the action of dead and live load.Therefore its strength and rigidity will reduce as time goes by.Fracture mechanics and damage mechanics are used to study on the corresponding problems in the operation of trussed combination arch bridge.Meanwhile one case is combined to research on the maintenance of this kind of bridge.It is significant. |
