摘要
针对钢管拱跨度长、桁高大、空管节段重的特点,通过比选钢管拱肋安装的2个可行方案,得出永和大桥钢管拱肋施工缆索吊方案在经济上优于竖转方案的结论。
In the light of the characteristics that the span length of the steel pipe arch of Yonghe River Bridge in Nanning is long, the trusses of the arch are high and the weight of the empty pipe segment of the arch is heavy, two feasible installation methods for the arch, i.e. the method of cableway lifting or vertical swivel erection, are compared. Conclusions through comparisons are generalized that for the installation of the Bridge, the cableway lifting is more cost-effective than the vertical swivel erection.
