Cable stayed bridge, also known as the cable-stayed bridge is of box girder with many cable directly to the towers is a kind of bridge, is by the pressure of the tower, tension of cable and bending bearing beams of a structure system. It can be considered as a continuous beam of multi span elastic supports for the cable instead of a pier. It can reduce the moment of the beam, reduce the height of the building, it reduce the weight of the structure and save the material. Stayed Bridge is a new form of bridge structure, The bridge structure special and complex forces, The deck transverse load and live load is to balance by tilting tower, By the general theory to analyze the cable-stayed bridge stayed bridge, The key is to consider the main tower tilt, Leaning further stress analysis, drawn stayed bridge mechanics analysis method.

Keywords: Cable force , dorsal column, mechanical analysis, stayed bridge.
