摘要
吊拉组合体系桥具有结构新颖、美观、受力合理、跨越能力强、抗风性能好、施工安全和造价低等优点,在软土地基和强风地区尤能突出其优越性,在超大跨桥型中极具竞争力.概述了吊拉组合体系桥的国内外发展现状,综述了吊拉组合体系桥在结构体系、计算理论、力学性能包括静力、动力和抗风性能等方面的研究进展,并指出了以后研究的主攻方向.
Due to its novelty and beauty, good structural performance, strong spanning capacity, good wind resistance, safe construction and economy etc. , cable-stayed-suspension bridge is very suitable for the natural condition such as soft soil foundation, violent typhoon etc. , and becomes the most competitive bridge type in the super-long-span bridge system. The development of the cable-stayed suspension hybrid bridges in the world is reviewed, and the research on structural systems, computational theory and the mechanical performances including the static, dynamic and the wind resistance etc. are comprehensively investigated, and the future development trend is pointed out as well.
