| 摘 要： | 对大跨度单片钢箱拱肋整体吊装过程中的吊索索力、拱脚两端位移、拱肋结构受力情况进行了静力分析计算，确定了合理的吊点位置。同时用近似公式法对钢箱拱肋的面内屈曲和面外侧倾进行了稳定性分析。通过有限元分析得到了大跨度钢箱拱桥的最佳起吊位置，为安全起吊提出了合理的建议。

| Abstract: | In this paper,we put emphasis on overall lifting of steel box arch,calculate the cable tension,the dis-placement and structure stress of arch,and determine the reasonable lifting point location.Buckling analysis of steel box arch rib and roll stability analysis of the outer surface are carried approximately,the best lifting position on overall lifting of steel box arch is founded,and reasonable suggestions for safe construction are presented. |
