%X Kriging algorithm builds varation model of regional variables and through which seeks for best linear unbiased estimator(BLUE) of unknown property.This paper combined with application of constructing 3D property model of water content within a certain engineering geological body,emphasized analyzing variation of regional variable under 3D circumstance,and adopted K-D tree to acquire neighborhoods quickly.Resolved negative weights during interpolation by linear program.The results show that 3D Kriging behaves better than 2D Kriging based on dividing layer for consideration of anisotropy and different scales on variation model.
