混凝土连续刚构不同合龙顺序仿真分析

摘要

以安康—汉中高速公路上的李家坝汉江大桥为研究对象,利用有限元软件进行模型计算,比较分析两种不同合龙顺序对主梁的应力和挠度、主墩位移的影响程度,最终选取合理的施工方案。%Taking Lijiaba Hanjiang Bridge of Ankang to Hanzhoung highway as the research object,this paper used the finite element software to make simulation calculation,compared and analyzed the stress and deflection of main girder,the influence of main pier displacement of two different closure orders,eventually chose rational construction scheme.
