混凝土面板堆石坝面板接缝的渗流计算模型研究

基于等宽缝隙稳定流的运动规律,建立了面板接缝的渗流计算模型,并以公伯峡水电站大坝为例,对模型进行了验证。结果表明,该计算模型考虑了接缝充填情况,可计算确定各种接缝渗流要素,揭示了在面板接缝止水失效情况下面板堆石坝的渗流变化规律。

Study on seepage calculation model of slab joints of CFRD

Based on the motion law of the same width slit steady flow ,the seepage calculation model of slab joints of CFRD is established,and this model is verified by the example of Gongboxia hydropower station dam. The results indicate,joints fill is considered in this caculation model ,seepage parameters of joints could be calculated and determined by the model ,seepage variation law of CFRD is revealed under the case of water stop in validation of slab joints.
