摘要
本文依据弥渡、永胜、楚雄台FSQ型浮子水管仪和个旧台JB金属摆倾斜仪原始记录图形资料,分析了澜沧——耿马大震前在图形上反映出的短临形变异常特征。并把这些特征同震源区岩体变化联系起来,探讨了震前孕震体变化过程与机理。
After analyzing the original data recorded by Type-FSQ float water piper from Midu,Yongsheng and Chuxiong three stations, and Type-JB metal pendulum tiltmeter from Gejiu station, the author picked out the abnormal patterns on deformation characteristics that appeared just before Lancang-Gengma great shock and later comparied these patterns with rock mass deformation in focal regions. Also the author made an approach on the mechanism and process of seismogenic varying body.
