|
摘要
以南台头闸大桥为工程背景,进行合理成桥状态的建模计算与分析。建立内力与线形双控制的索力优化模型,提出分步迭代的成桥思路,精确得到合理成桥状态。分析迭代塔、梁内力与线形、斜拉索索力的误差变化,研究成果对于独塔不对称斜拉桥合理成桥状态的确定具有参考意义。
Taking the Nantaitouzha Bridge as the engineering background, the modeling calculation and analysis of the reasonable bridging state are carried out. The cable force optimization model of internal force and line shape double control is established, and the bridge-forming idea of step-by-step iteration is proposed to accurately obtain the state of reasonable bridge. The error variation of the iterative tower, the internal force and line shape of the beam and cable tension is analyzed. The research results have reference significance for the determination of the reasonable bridge state of the single tower asymmetric cable-stayed bridge.
