| 摘 要： | 为尽可能减少对桥梁下部道路通行的影响和满足城市景观的需求，双柱花瓶墩预应力盖梁常作为城市高架桥的优选方案。传统的杆系结构受力分析无法准确模拟墩顶处预应力盖梁的受力特征，以某城市高架桥项目为依托，采用通用有限元软件针对墩柱及盖梁进行实体单元建模，应力和抗裂性等指标的验算结果均验证了设计方案的合理可靠。

| Abstract: | SIn order to reduce the influence on road traffic under bridge possibly and meet the demand of urban landscape, prestressed cap beam on double-column vase-shaped pier is frequently a preferred option of design of urban viaduct. Conventional force analysis of skeletal structures can not accurately simulate the stress characteristics of prestressed cap beam at the pier top, this article is based on some urban viaduct project, universal finite element software has been used to make solid element modeling in accordance with pier column and cover beam, the calculated results has verified the design scheme is rational and reliable, provide reference for similar engineering design. |
