摘　　要：基于等宽缝隙稳定流的运动规律,研究建立了混凝土面板极端破坏情况下面板接缝及密集裂缝型面板的渗流计算模型。借助于这些模型,使得面板接缝及密集裂缝型面板渗流的有限元模拟计算成为可能,从而为在面板发生极端破坏情况下面板堆石坝的有限元渗流分析提供了有效的途径。通过实例分析,还获得了在面板发生极端破坏情况下面板堆石坝的渗流变化规律。Based on the motion law of equal-width slit steady flow, the seepage calculation model simulating concrete face slab joints and face slab with dense cracks is studied and established under the extreme condition that slabs are destroyed. With the calculation model, the seepage simulation calculation FEM of slab joints and face slab with dense cracks becomes possible, and thus an effective way for seepage analysis with FEM of CFRD under the extreme condition of slabs to be destroyed is provided. With the model, the seepage change law of CFRD under this extreme condition is also studied through an illustration.
