摘　　要：为探究基础沉降对桥梁结构力学性能的影响,文章以某桥梁建设项目为依托,构建整个桥梁的模型,通过设置四种不同工况和基础沉降量条件,分析桥梁支座反力和控制截面反力变化规律。结果表明,基础沉降会对桥梁支座反力和控制截面应力产生影响,且基础沉降量越大,对桥梁支座反力和控制截面应力的影响程度越大。此外,不同基础沉降对桥梁结构力学性能影响极大,为确保桥梁安全,在设计和施工中应严格控制基础沉降。In order to explore the influence of foundation settlement on the mechanical properties of bridge structure,the model of the whole bridge is constructed based on a bridge construction project.By setting four different working conditions and foundation settlement conditions,the variation law of bridge bearing reaction force and control section reaction force is analyzed.The results show that the foundation settlement will affect the reaction force of the bridge bearing and the stress of the control section,and the larger the foundation settlement is,the greater the influence on the reaction force of the bridge bearing and the stress of the control section is.In addition,different foundation settlement has a great influence on the mechanical properties of the bridge structure.In order to ensure the safety of the bridge,the foundation settlement should be strictly controlled in the design and construction.
