application of pca-linmap coupling algorithm and model in determining weight of influence factors of surface deformation

Based on analyzing the limitations and shortcomings of the traditional method of empowerment, the PCA-LINMAP coupling model which uses to determine the weight of influence factors of surface deformation is established by principal component analysis and linear programming. This method completely considers the difference and the merits order of the samples, and overcomes the one-sidedness of the traditional method of empowerment in determining weight of index. The index system can reflect the object to being evaluated comprehensively and objectively, at the same time, provide an ideal way for improving the scientific of evaluation. Examples show that the method is scientific and reasonable; it also has extensive application value.
