| 摘 要： | 根据管道中恒定平行层流的泊松方程和热传导理论，采用三维有限元仿真方法，对含有冷却水管的混凝土坝的冷却水管中水温的变化规律进行了研究，分析及算例结果表明：水管中径向和轴向均有变化，但其变化值不大，对水管冷却的整体效果影响很小。

| Abstract: | Based on the theory of Poisson equation and heat conduction, the water temperature change rule in a concrete dan with water cooling pipes is studied in this paper using three dimensional finite element method（3DFEM）. The calculated results show that there are some temperature changes in water pipes along the pipe＇ s radial and axes direction, but the values are very small and the influence of general water cooling effect to concrete dam is very light. |
