摘要
以某顶推施工独塔钢箱梁斜拉桥为背景,通过不同方法对比确定合理成桥状态。在此基础上,应用ANSYS软件,考虑扁平钢箱梁的剪力滞效应,对斜拉桥的成桥状态进行荷载检验,确认桥梁营运期的安全可靠。
On the background of a incremental launching steel box girder cable-stayed bridge with sin-gle pylon,the paper determined the reasonable finished bridge state by comparison of different methods,based on which,using ANSYS and considering the shear lag effect,the paper tested the finished bridge state to make sure the safety and reliability in operation period.
