摘　　要：依据某景观河道人行廊桥的设计要求,提出钢管混凝土飞燕式斜拉拱的人行景观廊桥设计方案,其平面正投影为椭圆图形,拱肋侧立面为尾部翘起的飞燕式斜拉拱造型,廊桥顶部为马鞍抛物曲面的透明玻璃顶棚造型,飞燕式斜拉拱肋采用异形空间曲线钢管构形,廊桥桥面采用椭圆曲线形板梁结构。结合实际工程进行参数设计,建立MIDAS有限元模型,进行内力计算和模态分析研究,验证飞燕式斜拉拱的人行景观廊桥的结构合理性。According to the design requirements of a landscape river pedestrian corridor bridge,a design of pedestrian landscape corridor bridge with CFST and flying-bird cable-stayed arch is proposed.Its plane positive projection is ellipse figure,the side facade of arch rib is flying-bird cable-stayed arch with tail raised,the top of the gallery bridge is transparent glass ceiling with saddle parabolic surface,cable-stayed arch rib.The special-shaped space curve steel pipe structure is adopted,and the bridge deck of the corridor bridge adopts the elliptical curve plate beam structure.Combined with the actual project,parameter design,MIDAS finite element model,internal force calculation and modal analysis are carried out to verify the structural rationality of the pedestrian landscape corridor bridge with flying-bird cable-stayed arch.
