瀛洲大桥浇筑期间水化热温度场和温度应力分析

Analysis of Temperature Field and Stress by Heat of Hydration during Casting of Yingzhou Bridge

应用有限元分析程序ANSYS分析瀛洲大桥拱肋混凝土的浇筑温度场和温度应力,得到整个施工过程中温度场和应力场的分布规律,对高强度大体积混凝土的浇筑进行事前预测和浇筑进程控制具有重要的指导意义。

This paper analyzes casting temperature field and stress of arch rib concrete in Yingzhou Bridge by means of finite element analysis program and obtains the distribution rules of temperature field and stress field during the whole construction.The analysis in the paper shows important instructive sig-nificance for prediction in anticipation and casting process control of high-intensity and mass concrete.
