备注

以一沂沭断裂带剖面水准测线为例, 应用灰色关联分析方法研究了沂沭断裂带垂直剖面形变的空间分布特征。通过测点序列距离改化前后的关联度矩阵和关联序的差异研究垂直剖面的整体倾斜性变化特征,并研究了水准测线剖面形变时间上的时段性分布特征。实例表明灰色关联分析可以作为一种有实用价值的分析方法应用于断裂带垂直形变分析中。

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 showed 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.
