摘要
以已建独柱墩梁桥稳定性验算为工程背景,对其横向倾覆事故进行分析,利用有限元进行建模计算,探讨梁体自重、预应力、活载等不同因素对曲线梁桥抗扭稳定性的影响。
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.
