| 摘 要： | 我国地震灾害频发,城市高架桥梁作为交通生命线,抗震安全性尤为重要。目前我国城市高架桥梁普遍采用预制小箱梁和预应力混凝土大箱梁,从抗震分析角度考虑,根据两种结构型式抗震受力特点的不同,以及构造设计不同等方面,对两种结构进行比较,为地震高烈度区城市高架桥梁选型提供借鉴。

| Abstract: | Taking the construction project of Phoenix Valley Bridge in Liuzhou, Guangxi as an example, the two-level seismic design method is used to carry out the seismic response analysis and checking for the long-span continuous beam bridge containing the architecture on the bridge under the action of E1 and E2 earthquakes by using the response spectrum and nonlinear time-history method. Finally, the seismic performance and safety evaluation of the structure is given, which provides a useful reference for the seismic design of the similar bridges. |
