摘要
混凝土坝中的渗透水流通过参与热量传递与交换而影响坝体温度场的分布 ,坝体温度场又影响渗透水流及混凝土的渗透系数。本文从理论上分析了混凝土坝渗流场与稳定温度场相互影响、相互作用的机理 ,提出了混凝土坝渗流场与稳定温度场耦合分析的连续介质数学模型 ,讨论了该数学模型的有限元求解方法 。
The seepage flow in the concrete dam makes effect on the distribution of the temperature field in the dam by heat communicatoin. The temperature field in the dam also makes effect on the seepage flow and the hydraulic conductivity of the concrete dam. The mechanism of the action and reaction between the seepage and temperature field in the concrete dam is analysed according to the seepage characteristic of the concrete dam. The continuum mathematical model for coupled seepage and temperature field in the concrete dam is presented, is also discussed. The finite element numerical solution method of the mathematical model with an engineering example is given as well.
