摘要 本文提出了利用导电混凝土的电热效应,通过有限元分析计算以及由此而设计的实验得到导电混凝土导热系数的方法,并通过实验证明了该方法的可行性. Based on the Joule heating effect of the electrically conductive concrete, the finite element method is introduced to analyze the thermal conductivity of the material. The test results are given, which illustrates the method is successful and feasible.
