In view of the demand of super long span pedestrian landscape bridge with curved deck, this paper proposes a kind of cable-stayed and flying-brid arch bridge with Lissajous curved arch rib and double curved bridge deck. Its plane positive projection is Lissajous curve figure, the side elevation of the arch rib is the shape of the cable-stayed and flying-brid arch, and the arch foot cable and the upper space cable between the arch ribs are installed on the Lissajous spatial curved arch rib with concrete-filled steel tube to form a self balanced structure system, which floats and drags across the river. The main arch sling and the tail cable are installed, the double curved bridge deck and the central circular sightseeing platform are suspended, and multiple groups of spatial cables work well together to complement each other, with having complementary advantages. Combined with the actual project, the parameter design is carried out, the Midas finite element model is established, the internal force of the structure is calculated, the structural dynamic mode and stability analysis are carried out, the rationality of its structural performance is verified by analysis and research.
