摘　　要：在文献[3]的基础上,基于冷却水管与混凝土之间热量交换的平衡原理,提出水管冷却混凝土温度场问题有限元求解的改进迭代算法。通过试验验证及在工程中的应用,说明该算法不但在理论上精确、严密,而且具有很高的迭代计算效率和计算精度。On the basis of the work of the reference [3], the authors improved and suggested a iterative FEM procedure for solution to thermal problem in concrete with water-cooling pipes. The procedure is theoretically strict, totally solved the problem and has high accuracy and efficacy. Using the method and the calculation code, the results of an example and from the applications to one dam are given and illustrated。
