| 摘 要： | 吉河高速吉县枢纽A匝道2号桥是19跨(六联)现浇连续箱梁桥,该桥位于山西临汾枣庄河湿陷性黄土区内,现场采用满堂式支架进行的现浇混凝土施工,除对支架进行必要的强度、刚度和稳定性的受力验算外,还应重点对地基承载力进行分析计算,指出现浇箱梁施工中地基的处理方法不仅关系到支架方式的选择和布置,更关系到桥梁本身的质量和安全。

| Abstract: | In the collapsible loess area, this paper introduced the cast-in-place concrete construction withsite full support. It calculated the stress of necessary strength, stiffness and stability of the support, analyzed andcalculated the foundation bearing capacity emphatically. It also pointed out that the method of foundation treatmentin the cast-in-place box beam construction was not only related to the selection and arrangement of support mode,but also related to the quality and safety of the bridge itself. |
