摘　　要：文章在深入研究独柱墩混凝土连续弯箱梁桥失稳倾覆机制的基础上,利用相应的数值模拟法构建计算模型,验算实桥新增钢盖梁措施对抗倾覆稳定性的影响。结果表明,该方案符合现有规范条件,具备合理性和实用性,对同类工程具有一定的借鉴意义。Based on the in-depth research on the instability and overturning mechanism of single-column pier concrete continuous curved box girder bridge,the corresponding numerical simulation method is used to construct the calculation model,and the influence of the new steel cover beam measures on the anti-overturning stability of the actual bridge is verified.The results show that the scheme conforms to the existing standard conditions,has rationality and practicability,and has certain reference significance for similar engineering.
