计算混凝土水化热问题的有限元解

The Finite Element Method in the Pipe Cooling of the Concrete

用有限单元方法分别对一、二期冷却问题进行了研究 ,提出了相应的计算公式 ,编制了通用电算程序 。

The two stages (Ⅰ,Ⅱ) of cooling problem are studied, and relevant equations are derived while all possible factors are considered. On the basis of these equations, an universal computer program is worked out. Furthermore, practical alignment charts are inferred from to the calculating results, and the efficient fit curves are also given for the calculating temperature field in FEM and the designing in the civil engineering.
