摘要
分析了液态混凝土压强对钢管结构的作用,指出了哑铃形钢管拱先圆管后腹腔灌注顺序的合理性,提出了缀板采用对拉杆加固的方案,并分析了对拉杆间距、直径、材质等对缀板位移和应力的影响。
The effects of fluid concrete pressure on steel pipe structure are analyzed ,the reasonable sequence that web plates are poured after round pipe poured is pointed out in the paper. The schemes of reinforcing batten plates by tie bars are put forward and the effects of the space,diameter and types of tie bar on displacement and stress of batten plates are analyzed.
