【摘要】 通过对川滇菱形块体边界带上的 2 9个跨断层形变测量场地的观测资料进行处理、分析 ,根据确定的异常判据和指标 ,提取异常变化值。并对异常的时空分布进行综合分析 ,探讨地震发生前各个测量场地测量数据中所包含的前兆异常特征。同时对各断裂的群体形变特征进行分析。更多还原

【Abstract】 There are 20 surveying sites crossing faults distributed along the prim block boundaries to monitor the crustal deformation.Through our analysis to these observation data,we present several judging indexes to describe the abnormal precursors of deformation curves and get some of information value about active faults.With all deformation observing data,we analyze the abnormal distribution of crustal deformation and discuss the group deformation characteristic of the faults.更多还原
