The twin-tower three-span self-anchored cable-stayed bridge with main span of 1 600 m is taken as the basic study object. The finite element analysis model of the cable-stayed bridge system is built, and the structural static response is calculated in the condition of dead load, live load, wind load and various load combinations. Through the comprehensive structure calculation and parameter analysis of the preliminary design scheme, a variety of static mechanical properties of cable-stayed bridge with 1 600 m span are explained. At last, the technical feasibility of the conventional twin-towers three-span self-anchored cable-stayed bridge with steel box girder structure system is also discussed.
