| Abstract: | Taking the stability checking of one single-column curved beam bridge as the engineering background, this paper analyzes the lateral overturning accident of this bridge. The finite element is used to set up calculation model and the influence on torsional stability of curved beam bridge from beam weight, prestressed and live load are explored. |
