深圳北站超长结构温差收缩效应分析

摘要

Based on the research of temoerature variation effect,this oaoer does introduce the comolete finite element analysis on the temoerature variation and shrinkage effects of the whole structure,and based on the analysis results,the oaoer brings out some key measures to settle the oroblem of the temoerature variation and shrinkage effects. The oroject can be as reference for similar orojects.%在对国内外温差计算分析研究的基础上，参照温差收缩效应计算新方法，对深圳北站整体结构温差收缩应力进行了完整的有限元计算分析，并在此基础上提出了解决超长组合结构温差效应的措施，对面广量大的大体量超长结构设计具有一定的参考价值。
