摘要
拱桥施工阶段和成桥阶段边界条件有较大差别,拱肋稳定性不断变化。文章依托广州科学城四号空中连廊(开泰大道景观天桥)建设工程,采用有限元软件进行整体计算,完成不同施工阶段和成桥阶段的稳定性分析;对比分析施工过程中稳定性系数的变化和成桥阶段拱肋结构参数对稳定性系数的影响,对设计过程中采取构造措施提高拱桥的稳定性具有借鉴意义。
The boundary conditions of arch bridge in construction stage and completion stage are quite different,and the stability of arch ribs is constantly changing.Based on the construction engineering of No.4 space corridor(Kaitai Avenue Landscape Overpass)in Guangzhou Science City,the finite element software is used for overall calculation to complete the stability analysis of different construction stages and bridge completion stages.By comparing and analyzing the change of stability coefficient in the construction process and the infl uence of arch rib structure parameters on the stability coeffi cient in the completion stage,it is of reference significance to take structural measures to improve the stability of arch bridge in the design process.
