中文摘要：

为在有使系统凉下来的一根塑料管子的具体结构的水和热的热分析的一个三维的有限元素程序在这份报纸被介绍。程序在构造时期期间被用于温度的模拟和 Cao'e 水门的压力地。从计算结果，我们能发现没有管子，与塑料管子凉下来的水泥的温度和压力是比水泥的那些低得多的。而且，塑料管子不能被海水侵蚀。那是说，温度控制的好效果和裂开的预防能被完成，它为另外的类似的 nearshore 水泥工程提供一本有用参考书。

英文摘要：

A three-dimensional finite element program for thermal analysis of hydration heat in concrete structures with a plastic pipe cooling system is introduced in this paper. The program was applied to simulation of the temperature and stress field of the Cao＇e Sluice during the construction period. From the calculated results, we can find that the temperaiure and stress of concrete cooled with plastic pipes are much lower than those of concrete without pipes. Moreover, plastic pipes could not be corroded by seawater. That is to say, a good effect of temperature control and cracking prevention can be achieved, which provides a useful reference for other similar nearshore concrete projects.
