摘要:

拱塔斜拉桥兼具斜拉桥和拱桥的特点,其优美的造型很好的满足了桥梁设计对于美学的要求,使其往往成为城市的地标性建筑。本文以拱塔斜拉桥的发展历程为依据,总结了国内外该类桥梁的设计、建造情况,以此为基础,分析了不同拱轴线形对拱塔斜拉桥的桥面布置、拱塔受力的影响,得到了各类拱轴线形的优、缺点及受力特点；该结论可为拱塔斜拉桥的设计和后期维护提供一定参考。

Abstract:

The arch pylon cable-stayed bridge combines the feature of both arch bridge and cable-stayed bridge. It was always built as the city landmarks due to beautiful shape which could meet the aesthetic requirements of bridge design. The design, construction of this type bridge was summarized at home and abroad according the development course of arch pylon cable-stayed bridge in this paper, and then the influence of bridge deck layout, force of arch-pylon were analyzed base on different arch axis shape. Finally, the advantage, disadvantage as well as force characteristics of arch-pylon cable-stayed with different arch axis shape were put forward. The conclusions obtained in this paper could supply reference for the design and post-maintenance of arch pylon cable-stayed bridge.
