一种串联式自锚悬索桥合理成桥状态的确定方法及其系统
By using a linear finite element model of the main girder based on a single tower in a series self-anchored suspension bridge, the bridge alignment was calculated using the initial vertical component of the main cable and the suspender force. Corrections were made when the requirements were not met, which solved the problem of difficulty in determining the alignment of the main cable and the main girder in the completed bridge, and achieved rapid and accurate determination of the entire bridge's completed state.

AI Technical Summary
Determining the shape of the main cable and the final bridge alignment of the main girder in a series self-anchored suspension bridge is difficult, especially the possibility of vertical displacement of the main cable anchorage point at mid-span, which makes it difficult to determine the final bridge alignment.
Based on the linear finite element model of the main girder of a single tower, the initial vertical component force of the main cable and the suspender force are obtained to calculate the bridge alignment. If the requirements are not met, corrections are made until the main girder alignment requirements are met, and the final bridge state is gradually obtained.
This paper presents a clear and high-precision method to quickly determine the completed state of a series self-anchored suspension bridge, avoiding inefficient and repeated trial calculations, and ensuring that the deflection of the main beam and the rotation angle at the beam end meet the design requirements.
