According to the geometric figure of three-leaf rose curve, this paper puts forward a flying-bird type cable-stayed arch bridge with curve shaped CFST rib, which has beautiful appearance and one leads three banks.The space cables are set between linear ribs resist negative bending moment, tie feet positive moment. On inclined pylon at tail bridge, stay-cables arranged balance thrust, suspension...
