灵江特大桥栈桥设计与计算

The design and calculation of trestle of Lingjiang grand bridge

结合工程概况,从梁Ⅰ40a工字钢检算、Ⅰ16工字钢栈桥横向分配梁、Ⅰ28b支座垫梁验算、钢管桩自由长度及稳定性验算、栈桥钢管桩单桩承载力计算等方面介绍了栈桥的设计与计算过程,以供类似桥梁工程的设计参考。

Combined with practical engineering condition,the author introduces the design and calculation process of trestle from checking Ⅰ40a steel beam,transverse beam distribution of 16 Ⅰ-type steel trestle,checking Ⅰ28b bracket cushion beam,checking free strength and stability of steel tubular pile,calculating single-pile bearing capacity of trestle＇s steel tubular pile,which to offer a reference for the design of similar bridge engineering.
