摘要
Taking the leveling line crosses the Yishu fault zone profile as an example,we applied grey correlation analysis to study the deformation spatial distribution characteristics of the Yishu fault vertical profile. The difference of correlation degree matrix and relational order before and after the distance correction on measuring points sequence show ed that the Yishu fault zone profile had the characteristic of overall tilt in different periods. Through studying the vertical profile curve among every year,we found that the deformation of this profile had the characteristic of period distribution. The example shows that the grey correlation analysis is a practical analyze method in the application of vertical deformation analysis on the fault zone.
