摘要
对于中小跨径的混凝土连续梁桥,工程界在设计与施工中一般很少考虑混凝土徐变效应的影响,本文从混凝土徐变效应的计算理论与方法出发,对于唐万大桥采用考虑混凝土徐变效应的有限元分析,并得出较有意义的结论,可供广大工程技术人员参考。
Creep effect has been seldom taken into account on design and construction of small and medium-sized span concrete girder bridges in engineering field.Finite element analysis which involves concrete creep effect is built for Tangwan Bridge based on calculation theory and method of concrete creep effect in this paper.Some significant conclusions are got here and it is also a reference for the engineers.
