| 摘 要： | 通过对面板裂缝特征及其渗流形态的分析，基于等宽缝隙稳定流的运动规律，研究建立了堆石坝混凝土面板裂缝的渗流计算模型。借助于该模型，使得面板裂缝渗流的有限元模拟计算成为可能。运用该计算模型，通过实例分析，本文获得了在面板产生大量裂缝情况下（非常工况）面板堆石坝的渗流变化规律。

| Abstract: | Based on the motion law of equal-width slit steady flow, by analyzing the characteristic of the concrete face slab cracks and its seepage configuration, the seepage calculation model for the concrete face slab cracks has studied and established. With this model, the calculation of seepage FEM simulation for the slab cracks become possible. Using this model, illustrated by an example, the seepage change law of CFRD under the extreme condition that there are so many cracks in the slab is obtained. |
