摘　　要：渗流场对温度场的影响主要通过水流动时挟带热量的热对流作用。渗流速度不同,对流热传递热量的速度不同,温度场受影响程度也不同。该文对渗流温度耦合模型展开数值模拟,应用物理模型试验成果进行了对比验证,并着重分析了不同渗透系数下温度场的变化特征,求出渗流区热量传递的所占比重。The influence of seepage on temperature field is mainly through heat convection caused by water flowing. With the different penetration velocity, the speed of convection heat transfer would be different, and the effected degree of temperature field would be also different. This paper expounds the mathematical coupling model of seepage field and temperature filed, implements numerical simulation, and the physical model test is used to verify the simulation results. Focusing on the analysis of the characteristics of temperature field under the different permeability coefficient, the heat proportion contributed by heat convection is calculated.
