摘要: 阐述了有关于渗流场数值分析的理论基础，结合某抽水蓄能电站上下库的地质和水文地质条件，使用ADINA有限元软件建立了坝体三维数值模拟模型，计算分析了各种运行工况下的上库和下库的渗流量和渗流场的分布特征。然后在上水库水位不断变化下的情况下，分析库水位下降过程中渗流参数变化对坝体自由面变化规律，计算得出水位下降各个工况下的等水头线，浸润线，渗流量等渗流关键因素，得到在水位下降过程中，渗流量不断减小但是浸润线基本保持不变。
Abstract: The theoretical basis of numerical analysis of seepage field is reviewed. Based on the geological and hydrogeological conditions of upper and lower reservoirs of a pumped storage power station, the three-dimensional numerical simulation model of dam was established by using ADINA finite element software. The distributions of seepage and seepage field of upper and lower reservoirs under various operating conditions were calculated and analyzed. Under the condition of changing the water level of the upper reservoir, the variation law of the seepage parameters in the reservoir water level is analyzed, and the change of the free surface of the dam is calculated. The water level decreases, such as the head line, the infiltration line and seepage flow. It is concluded that the seepage flow is decreasing but the infiltration line remains essentially unchanged during the descent of the water level.
