摘　　要：介绍了万安溪面板堆石坝面板上部裂缝的情况，讨论了面板混凝土的干缩变形、两岸坝体的不均匀沉降、面板的拉应力区域和气温骤降等影响因素，初步分析了裂缝的成因以及裂缝对运行的影响，提出了今后应高度重视裂缝发展趋势和作深入理论分析的建议。The characteristics of cracks in the upper face plate of Wananxi CFRD are intruduced in this paper. the genetic analysis is made based on drying shrinkage of the concrete face plate, differential settlement of the dam. tensile stress zones of the face plate. the sudden drop of air temperature, etc. Suggestions are proposed for further monitoring and analysis.
