摘　　要：针对深圳北站枢纽西广场超长结构,考虑收缩、徐变影响综合取定温度计算值,利用有限元软件MIDAS对结构在温度作用下的内力及变形进行计算,分析了其对梁柱的影响,在实测和计算分析结果的基础上,总结得出超长混凝土楼板施工阶段的温度应力分布规律,提出了有关设计和施工建议,可供类似工程参考。In the case of Shenzhen North Station transport hub west square, the temperature values is determined,including the effects of concrete creep and shrinkage, the internal force and deformation of the structure are analyzed by MADIS,analyses the influence on the behavior and the strength of beam columns, comparing the test results with analysis results. Thermal stress of super-long concrete floor distribution is drawn based on analysis and comparison. The result of analysis and calculation in this article provides recommendations for future similar projects.
