对实际工程中常用大体积混凝土水管冷却曲线的拟合

The curves of regression for cooling problem of the mass concrete

本文在用有限元法对一、二期水管冷却问题研究的基础上对曲线加以回归 ,得出拟合后的回归曲线用于等效热传导方程中 ,便于工程设计及有限元法计算温度场之用。

In this paper,the curves of regression for two(Ⅰ,Ⅱ)cooling problem of the mass concrete were given.The efficient fit curves were also given for the calculating temperature field in Finite Element Method and the designing in the Civil Engineering.
