T he main bridge of Yunfei Bridge in Jinzhou City is a single pylon cable‐stayed bridge with double cable‐planes and with span arrangement of 108+92 m .The bridge is designed as a combined continuous girder and cable‐stayed bridge ,with separated pylon and girder .The main girder adopts the double‐edged steel box beam structure with a height of 2 .8 m .The standard bridge deck width is 30 m ,with two‐way 2% transverse slopes .The pylon is formed of two sets of arches :an outer arch and an inner arch ,the outer arch is 65 .5 m high and inclines 8° ,the roots of which are spaced at a distance of 38 .0 m .The inner arch is 54 .2 m high and inclines 15° ,the roots of which is spaced at a distance of 25 .0 m .Between the outer and inner arches ,25 tensile connect‐ing struts and 2 compressive struts were installed .The stay cables are the finished PPWS cables and the cross section of the arch rib adopts box section .At the pylon roots ,the 100 mm diameter anchor bolts are used to anchor the pylon legs to the top of the pier cap ,and the threaded rein‐forced bars are added to supply prestress .A total of 20 pairs of stay cables w hich are made up of high strength galvanized parallel wires ,are tensioned between the pylon and the girder .The foun‐dation of the arch pylon is formed of four separated group pile foundations with pile diameter of 1 .5 m.The pylon is constructed by the scheme of being assembled horizontally and vertically rotated . T he construction method of using the inner arch to lever the outer arch is innovatively employed .%锦州市云飞大桥主桥为双索面双套拱独塔斜拉桥，跨径布置为（108＋92） m ，采用连续梁—斜拉桥协作体系，塔梁分离。主梁采用双边钢箱主梁结构，梁高2．8m，桥面标准宽度30m，设双向2％横坡。桥塔采用双钢箱套拱结构，外拱塔高65．5m，倾角8°，塔根间距38．0m ；内拱塔高54．2m，倾角15°，塔根间距25．0m ；内、外拱塔间布置25根受拉的连杆和2根压杆，分别采用平行钢丝成品斜拉索和钢箱结构；塔根采用φ100 m m的锚栓将塔柱锚固于承台顶面，并采用螺纹粗钢筋施加预应力。全桥共设20对塔梁间斜拉索，采用高强镀锌平行钢丝索。拱塔塔基为4个分离式的群桩基础，桩基直径1．5 m。设计采用卧式组拼、整体竖转的桥塔施工方案，并提出利用内拱塔起扳外拱塔的施工工法。
