摘要
重点介绍了山西省朔州市安泰街跨七里河的一座重要城市景观桥梁-安泰街大桥的结构设计和计算分析。该桥主桥采用三跨桁架拱梁组合体系,主拱采用内倾式无风撑结构,斜拉索扇形布置,桥梁造型新颖美观。通过静力、稳定和疲劳计算分析,验证了该设计方案的合理性及安全性,可为同类桥型设计提供参考。
The article focuses introduction on the structural design and calculation analysis of Antai Street Bridge-an important urban landscape bridge crossing the Qili River in Antai Street of Shuozhou City in Shanxi Province. Its main bridge is a three-span truss arch-beam composite bridge. Its main arch is an introversive no-wind bracing structure. Its stayed cables are arranged in the fan shape. The bridge modeling structure is novel and delight. The static analysis, stable analysis and fatigue calculation analysis can verify the rationality and safety of this design scheme, which can be referred for the design of the similar bridges.
