摘　　要：桥梁结构在长期服役过程中受外界环境、材料性能与荷载作用等共同影响,导致桥梁结构的耐久性、安全性随时间推移而逐渐降低,影响桥梁结构运营的安全性。因此,为了确保桥梁结构在服役期间的安全性,需要在桥梁设计时重视安全性与耐久性设计。Affected by the external environment, material properties and loads, the durability and safety of bridge structure was gradually decreased, which resulted that affected the safety of bridge structure operation. Therefore, we should pay attention to the safety and durability in bridge design in order to ensure the security of the bridge structure during service period.

关 键 词：桥梁工程 安全性 耐久性 稳定性
