摘　　要：高混凝土面板堆石坝的面板变形应考虑混凝土结构自身因素及水压、坝体沉降、水平位移、降雨量和面板温度等外部作用的影响。通过聚类分析将面板样点分成3组,其中第3组占面板的主要部分。由相关性分析发现坝体水平位移跟水压相关性好且显著。对第3组面板变形的4个影响因子进行主成分分析,发现堆石体变形是影响面板变形的主要因子。The study of panel deformation of high CFRD should consider the impact of concrete structure of darn, water pressure, dam settlement, horizontal displacement, rainfall and panel temperature. By cluster analysis, the samples on panel are divided into three groups, the third group accounts for the major part of panel. The correlation coefficient analysis finds that the horizontal displacement of dam has a significant correlation with water pressure. The main ingredient that characterizes the deformation of panel in third group samples is extracted from four impact factors by principal component analysis, and confirms that the rock-fill deformation is the main factor affecting the deformation of panel.
