| Abstract: | The cable force calculation is the key technology link for the secondary cable adjustment of cable-stayed bridge.The article,with a cable-stayed bridge using the secondary cable adjustment for the construction as the example,described the method of applying and combining the forward iteration method with the impact on the matrix to calculate the cable force for the secondary cable adjustment construction of cable-stayed bridge,and through the construction process simulation analysis,it verified that the calculation results of this method are accurate,able to effectively control the internal force and linear shape of cable-stayed bridge construction process,so as to ensure the achievement of the designed finished-bridge state. |
