The accuracy analysis on Kriging estimation of the geotechnical parameters random fields and a approach to the outliers processing

摘要: 阐述了克立格方差的特点，并结合实际对岩土参数随机场空间最优估计的局部估计精度进行了分析，探讨了影响岩土参数空间最优估计精度的特异值的处理方法。研究结果表明，对存在特异值的岩土参数随机场进行估计时，应用指示克立格法能够获得符合实际的空间最优估计效果。

Abstract: In Kriging estimation on the geotechnical parameters ,Kriging variance has a special meaning.This paper elaborates the characteristics of Kriging variance,and analyses systematically the locally estimated Kriging accuracy of the random fields of geotechnical parameters in the light of a practical example. The concrete procedure to deal with the outliers which exert a great influence on estimated Kriging accuracy of the geotechnical parameters has been preliminarily researched in the paper too.
