本文介绍即将成为世界第一大跨度的钢筋混凝土箱拱用劲性骨架施工时的稳定性分析方法,给出了考虑几何非线性和钢管混凝土应力历程的计算结果,并用模型试验验证了所编制的 LSB-NS 计算程序,最后提出了相应的结论和建议。
This paper introduces the stability analysis method of the rigid skeleton construction of reinforced concrete box arch that will soon become the first span in the world. The calculation results of considering the geometric nonlinearity and the stress history of CFST are given. The model tests verify that the proposed LSB -NS calculation program, and finally put forward the corresponding conclusions and recommendations.
