摘　　要：以一典型的超长钢筋混凝土框架结构工程实例为基础,通过控制结构总长度,采用黏弹性理论,利用通用有限元分析软件ANSYS进行热-结构耦合分析,揭示结构浇筑过程中总长度对温度应力和变形特征的影响,可供实际工程参考。Based on a typical example of super long concrete frame structure engineering, by changing the total length of the structure, uses ANSYS which is the general-purpose finite element analysis soil-ware to do thermal structure coupling analysis on viscoelastic theory, The result for practical engineering reference reveals the total length＇s impact on the temperature stress and deformation characteristics in pouring process.

关 键 词：超长混凝土结构 硬化阶段 温度应力 黏弹性理论
