摘　　要：国内外混凝土面板堆石坝安全评价中,定量并直观地评估监测值的方法并不多。本文通过面板挠度、坝体沉降、周边缝变形、大坝渗流及水平位移等重要的面板坝监测项目,建立监测项目与各自主要影响因子间最紧密的回归线,并作为大坝安全状态划分的基准线;计算出各样点与基准线的距离,从而确定监测项目的取值范围,并选定一个正常状态的参考样点,利用函数转换统一了级别的划分标准,并定量划分为5个级别。在此基础上对各评价指标赋权重值,并结合大坝监测的部分数据,评价了水布垭面板堆石坝的坝体安全状况;同时利用其他评价方法对各坝体的评价结果与该方法作比较,证实该方法是可行的。For the safety evaluation of the status quo of domestic and foreign CFDR, quantitative and visually assess the monitoring value is not too much. In this paper, through collecting the slab deflection, dam settlement, peripheral joints deformation, dam seepage and horizontal displace- ment of CFRD important monitoring project information, it established the most close regression line between the monitoring projects and each main affecting factor and used as dam safety status baseline. It calculated the distance to the reference sample point and the reference line so as to deter- mine the range of values of the monitoring items, and selecting a normal state of the reference samples, using the function to convert the unified lev- el division standards and quantitatively divided into five levels. Empowers the weight value of each evaluation, and on this basis the part of the pro- ject team in Shuibuya dam monitoring data to evaluate the Shuibuya CFRD dam safe condition ; while taking advantage of other evaluation methods for each dam the evaluation results of the comparison, it confirmed that the method was feasible.
