摘要
拱塔斜拉桥兼具斜拉桥和拱桥的特点,其优美的造型很好地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。现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,从而得到了各类拱轴线形的优、缺点及力学特点。该结论可为拱塔斜拉桥的设计和后期维护提供一定参考。
The arch-pylon cable-stayed bridge combines the features of both arch bridge and cable-stayed bridge.The beautiful shape splendidly meets the aesthetic requirement of bridge design,which often makes it become the landmark building of a city.Taking the development process of arch-pylon cable-stayed bridge as the basis,the design and construction of this kind of bridge at home and abroad are summarized.On this basis,the influences of the different arch axis shapes on the deck layout and the arch-pylon force of arch-pylon cable-stayed bridge are analyzed so as to obtain the advantages,disadvantages and mechanical characteristics of various arch axis shapes.This conclusion can provide some reference for the design and late maintenance of the arch-pylon cable-stayed bridges.
