摘要
基于Monte Carlo思想对斜拉索索力随机误差进行了模拟,对千米级斜拉桥按照第二类稳定问题的求解方法对其施工过程进行了模拟分析,主要考察了斜拉桥处于最大双悬臂和中跨最大单悬臂状态时最不利施工工况下结构的极限承载力,给出了不同施工误差下大跨径斜拉桥荷载安全系数的比较和分析结论。
Based on Monte Carlo thought, the paper simulates the random errors in the cable＇s force, has a simulation analysis of the construction process of a-thousand-meter-scale cable-stayed bridges, according to the resolution methods for the second stable problems, inspects mainly the ultimate bearing capacity of the structure in the worst construction conditions, when the double canilever and the single canilever of the middle span are maximized, provides comparison and analysis concludes of the loading safety factors of large span cable-stayed bridge tinder different construction errors.
