| 摘 要： | 选择某9×20 m混凝土连续空心板梁为工程背景,研究连续空心板梁拓宽时新旧地基沉降差对结构受力的影响,利用有限元软件建立模型,分析了地基不均匀沉降对旧桥拓宽影响,分析结果表明：地基不均匀沉降对桥梁拓宽影响较大,应确定地基不均匀沉降的控制值。提出减少不均匀沉降的措施,为施工提供参考。

Study on effect of foundation settlement on widening continuous hollow slab |

| Abstract: | In order to study the structure stress effect of foundation settlement difference on widening continuous hollow slab,we chose a 9×20 m prestressed concrete continuous hollow slab bridge as an example,used a finite element software build a model,and analyzed the effect of foundation settlement difference on widening an old bridge.The results show that the impact of foundation settlement difference was great,and the control values of foundation settlement should be determined,and measures are presented to reduce the foundation settlement,which can provide a reference for similar projects. |
