京哈高速公路拉林河特大桥钢栈桥设计

Design of Steel Trestle of Lalinhe Grand Bridge over Beijing-Harbin Expressway

以京哈高速拉林河特大桥钢栈桥为研究对象,通过有限元计算,详细阐述了钢栈桥结构的设计要点和受力特性,对钢栈桥的强度、刚度和稳定性能进行了受力分析,对其横向抗倾覆稳定性能进行了验算,并对钢管桩进行设计,可为类似工程的设计提供借鉴。

Taking the steel trestle of Lalinhe grand bridge over Beijing-Harbin expressway as the research object,the design key points and stress characteristics of the steel trestle structure are elaborated in detail through the finite element calculation,the stress analysis on the strength,rigidity and stability performance of the steel trestle is carried out,the checking calculation on the transverse anti-overturning stability is performed,and the steel pipe pile is designed,which can provide reference for the design of similar projects.
