为了利用有限的大坝位移观测资料分析大坝内部位移场情况，将基于空间变异理论的克里金法应用于大坝安全监测位移场，进行插值拟合计算位移等值线。克里金法是以变差函数作为基本工具，在研究区域化变量的空间分布结构特征规律性的基础上，综合考虑空间变量的随机性和结构性的一种数学地质方法。应用克里金法结合某大坝的位移观测资料绘制等值线图，结果表明，该方法能有效地应用于大坝安全监测数据插值拟合，形成位移场等值线，并为大坝安全监测可视化提供基础数据。

In order to use the limited observational data of dam displacement analysis of situations of internal displacement ,This pa‐per applies Kriging ,based on spatial variability theory method to dam safety monitoring displacement to contour interpolation fitting . The Kriging method is based on the variogram function as basic tools .Research is done on regionalized variables based on the struc‐tural characteristics of the spatial distribution regularities of considering randomness of spatial variables ,and the structure of Mathe‐matical Geology methods .This paper studies a large hydropower station in China .It draws a contour map of the displacement field by Kriging .Compared with the numerical model ,it shows that the method can be effectively applied to dam safety monitoring data interpolation fitting ,form the contours of displacement ,and to provide a basis for the visualization of dam safety monitoring data .
