摘要
明珠大桥主桥为85 m下承式斜靠钢拱桥。文章采用有限位移理论法,使用大型有限元计算程序进行结构分析,采用三维有限元模型计算,考虑荷载的空间效应,同时根据施工架设过程,形成各阶段的计算图式,详细分析结构各施工阶段的应力和位移变化情况,桥梁三维静力计算结果均能满足规范要求。
The main bridge of Mingzhu Bridge is a 85 m down-supported steel arch bridge.It adopts the finite displacement theory method,uses large finite element calculation program for structural analysis,uses three-dimensional finite element model for calculation,considers the space effect of load,and forms the calculation diagram of each stage according to the construction and erection process.This paper analyzes the stress and displacement changes in each construction stage in detail,and the three-dimensional static calculation results of the bridge can meet the requirements of the specification.
