预应力混凝土连续刚构桥预拱度仿真模型分析

摘要

利用设计资料建立有限元仿真模型,研究了预应力混凝土连续刚构桥型的东庄禾5号桥在采用悬臂施工过程中的预拱度设置问题,为东庄禾5号桥在施工中的线形控制提供理论和数据方面的支持,同时为预应力混凝土连续刚构桥施工的有限元仿真模型分析预拱度提供一个有益的案例。%This paper established finite simulation model using design materials,researched the camber setting problem of East Zhuanghe No.5 bridge of prestressed concrete continuous rigid frame bridge in the process of using cantilever construction,provided theory and data support in the construction of linear control of East Zhuanghe No.5 bridge,at the same time provided a useful case for analysis on finite element simulation model in the construction of prestressed concrete continuous rigid frame bridge.
