通过对鲜水河断裂带多年跨断层形变测量资料的分析，揭示出鲜水河断裂带不同部位的形变特征，断裂带破裂区表现为较高速率的蠕滑运动，其运动速率又以极震区为中心向两侧衰减，“闭锁区”则具有运动停滞的特点，并有明显的分段性。断层形变的特殊形态还与地震有一定的关系，如每当形变出现“Ｖ”（或倒“Ｖ”）字型时，会有中小地震对应；断层扭动反向与变化也与地震有关。 Through the analysis of the data of cross-fault deformation measurement in Xianshuihe fault zone for many years, the deformation features of different parts of the Xianshuihe fault zone are revealed. The rupture zone in the fault zone shows a relatively high rate of creep movement. Area as the center to both sides of the attenuation, “lockout area” has the characteristics of motion stagnation, and obvious segmentation. The special form of fault deformation is also related to earthquakes. For example, whenever a “V” (or inverted “V”) character appears in deformation, there will be small and medium earthquakes corresponding to them. Fault reverse and change in fault are also related to earthquakes.
