摘要
利用SAP2000软件有限元的方法进行箱型拱桥分节段安装斜拉扣挂计算,能够得到可靠的扣索索力结果,为选择合适的扣索提供依据。并能得出各施工阶段拱箱的受力,以便对拱箱在施工阶段中进行验算,保证拱箱在施工阶段的安全性。
The finite-element method of SAP2000 can not only calculate the cable force of cable-stayed buckle in the segment installation of basket type arch bridges and provide reliable reference for choosing appropriate buckle cable,but also shows the arch box's stress in each construction stage,which is helpful for the verification during arch box construction,and hence to ensure safety of the arch box.
