| Abstract: | Taking the main bridge of the 4th Xiangtan Xiangjiang River Bridge as the research obiect, this paper establishes a three-dimensional spatial finite element model for cable-stayed arch bridge, using the universal finite element program, calculates the stability safety coefficients of the structure of the bridge and also analyzes the instability characteristics thereof. The results of calculation in the paper may provide reference for the construction, health inspection and maintenance of the bridge at operation stage. |
