| Abstract: | Taking the 260 m half-through concrete-filled steel tube arch bridge as an example,the author shows the analysis method of the structural stability,and analyzes the features of the structural stability,the results show that the instability problems of the bridge type mainly occurs in the service stage and the stiffness of the arch rib determines the structural stability. |
