流溪河特大桥有限元仿真分析

Finite Element Simulation Analysis of Liuxihe Rigid-frame Bridge

有限元仿真分析是施工监控过程中重要的一环,为节段施工过程中结构安全和主梁最终达到设计线形提供理论分析依据。针对流溪河特大桥的实际情况,利用Midas/civil进行全桥梁单元模型的有限元仿真分析,分析中考虑该桥的施工过程及后期的收缩徐变效应。

Finite element simulation analysis is an important part of the construction monitoring,it is a theoretical basis for the structure safe in the progress of segmental construction and the best alignment design of the beam.With reference to the actual conditions of Liuxihe Rigid-frame bridge,the beam element model is used to realize the finite element simulation analysis of overall bridge structure,in which the construction process effect、shrinkage and creep effect are considered.
