针对混凝土面板堆石坝面板接缝与面板裂缝的特点,基于等宽缝隙稳定流的运动规律,结合混凝土面板堆石坝的渗流机理,研究建立了面板接缝及面板裂缝的渗流计算模型,并用实例进行了验证.结果表明将等宽缝隙稳定流运动规律应用到面板接缝止水失效且面板产生裂缝情况下面板堆石坝的渗流分析中,可以获得较为准确的结果.且此方法计算过程简单,计算效率高,具有很大的实用性.

Based on the motion law of equal-width slit steady flow,according to analyze the characteristics of the face slab joint and crack of concrete face rockfill dam,combined with the seepage mechanism of concrete face rockfill dam,seepage calculation model for face slab joint and crack is studied and established,and the model is verified by examples.The examples indicate that comparatively accurate result is obtained by applying the motion law of equal-width slit steady flow to seepage analysis of concrete face rockfill dam under the condition that the face slab joint waterstops are in failure and the face slab has cracks.The calculation via this method is simple; the model is of high computational efficiency and of prodigious practicality.
