| 摘 要： | 许多大坝只在坝体内布置有限的温度计，并且许多运行多年的大坝更因坝体内的温度计损坏而无法知道坝体温度场状况，为此根据坝体温度计实测资料和边界温度条件。着重分析气温、水温及水泥水化热3个主要因子对坝体温度场的影响，建立坝体温度场时空分布模型。通过实例分析表明，温度场的回归拟台曲线与实测值曲线拟合得较好。

| Abstract: | There are limited thermometers in many dams, and the thermometers in many old dams were damaged, so we cannot know the state of dam temperature field. In this paper the distribution model about time and space of dam temperature field is established based on actual statistical data and temperature boundary condition. Through example analysis, the regression curve line is fit to the actual statistical data. |

| Keywords: | temperature field distribution model about time and space of temperature field regression curve line |
