梁拱组合式桥梁吊杆内力的优化分析

Optimization Analysis of the Internal Force of Hangers in Camber Composite Bridge

通过对梁拱组合式桥梁成桥状态目标的优化分析,可以得到不同施工阶段合理的吊杆内力。结合嘉兴市迎宾大桥主跨工程实践中施工控制分析,介绍了成桥状态的最优化原理及施工优化分析方法,为同类桥梁的设计和施工提供了参考。

Rational internal force of hangers under different construction stage can be obtained through optimization analysis of the object under the finished bridge condition of the camber composite bridge. With the analysis of construction control in this project, the author introduces optimization theory of the finished bridge and optimization analysis under construction stage, and also provides reference for design and construction of the same type of bridges.
