摘要
拱轴系数m作为悬链线的线形特征,其对于悬链线主拱圈的影响至关重要。采用大型分析软件Ansys,针对600m跨钢筋混凝土拱桥进行拱轴系数优化设计,得到了主拱圈截面的拱轴系数对于主拱圈的影响,结果表明拱轴系数应采用相对较大值。
as an axis characteristic of catenary,the arch axis coefficient m is very important to the catenary arch. For large span reinforced concrete arch bridge of 600 m,arch axis coefficient optimization design is done by using the software Ansys.The influence coefficient of arch axis of main arch section for the main arch is obtained.The results show that the larger the value of coefficient of arch axis should be used.
