摘要
对滇西地区 6个断层形变测量场地的资料进行处理。获取研究区每月的总体运动速率 ,绘制每月的形变等值线图 ,求出每幅图的容量维。探讨容量维、形变等值线和总体运动速率在历次地震前的演变特征。
We process the data measured from 6 deformation surveying sites crossing fault located in Yunnan regions and get the results of movement rates of faults per month for each site.Based on these results,we drew the contour map and then calculate the capacity dimensions for each picture.The factors such as the capacity dimension,contour of deformation and movement rates of blocks show the characteristic changes before earthquakes.
