【摘要】 本文采用有限元分析法对安徽省境内G30连霍高速与G3京台高速交汇处朱圩子互通立交独柱墩曲线梁桥(A匝道、B匝道、G匝道、H匝道)的抗倾覆能力进行验算分析,并结合桥梁结构特点,提出桥梁抗倾覆加固方法,以此提高独柱墩曲线梁桥的抗倾覆稳定性能,进而使得桥梁结构受力更加合理。更多还原

【Abstract】 This paper uses the finite element analysis method to resist the overturning of the single-column curved beam bridge(A ramp,B ramp,G ramp,H ramp) of the intersection of G30 Lianhuo Expressway and G3 Jingtai Expressway in Anhui Province. The capability is checked and analyzed,and combined with the characteristics of the bridge structure,the anti-overturning reinforcement method of the bridge is proposed to improve the anti-overturning stability of the single-column curved beam bridge,which makes the bridge structure more reasonable.更多还原
