龙滩碾压混凝土坝稳定渗流场与稳定温度场耦合分析

渗流通过参与热量传递与交换影响温度分析，温度通过改变介质渗透系数和温度势梯度引起水流运动来影响渗流场，两者相互作用最终达到珠渗流场和温度场,应用混凝土坝渗流场和温度场耦合分析的数字模型，进行了龙滩碾压混凝土重力坝稳定渗流场和稳定温度场的耦合分析，结果表明，耦合作用使龙滩坝稳定温度场温度普遍降低，稳定渗流场水头普遍升高。

Analysis of Coupled Stable Seepage and Temperature Fields in Longtan Roller Compacted Conctere Dam

Seepage influences on the temperature distribution by means of heat transfer and communication, temperature influences on seepage field by changing the hydraulic conductivity and inducing fluid flow because of the temperature potential, thus finally approaching the stable seepage and temperature fields. Coupled seepage and temperature fields in Longtan roller compacted concrete gravity dam are analyzed by applying the mathematical model for coupled seepage and temperature fields in concrete dam. It can be shown that the interaction between seepage and temperature makes the stable temperature of Longtan dam lower generally, and the hydraulic head of stable seepage field higher generally.
