| 摘 要： | 计算比较了不同边界条件下混凝土浇筑层温度场的理论解答，证实目前运用的第三类边界条件下的解答在边界附近严重“失真”，而第一类虚边界条件下的解答不但形式简单，计算方便，而且结果稳定，能反映温度场的边界特征。

| Abstract: | Based on comparison of calculating results of concrete lift temperature Solutions with different boundary conditionts. it is proued that the temperature Solution of the lift with the third type boundary condition could not give a reasonable results in the region close to the lift surface. and the solutin with uirtual Dirichlet type boundary condition is a better solution to study concrete lift temperature field because it not only has a simple form but also correctly shows the features of the field at and near the bonudary surface. |
