本文通过对石屏—建水断裂自化念到建水各段新活动特征与性质的分析,认为在同一地质历史时期内断裂不同地段的活动特征及性质不同;在不同地质历史时期断裂上同一地段的活动特征与性质亦不同。并得出水平运动强烈的地段并不一定说明地震的危险性,而断裂上新活动性质发生改变的畸变部位,恰是地震发生场所的结论。 Based on the analysis of the characteristics and the nature of the new activities of ShiPing-Jianshui fault self-reformation and Jianshui section, this paper argues that the characteristics and the nature of the activities in different sections of the fault during the same geologic history are different. Lot features and characteristics of the activities are also different. It is concluded that the strong horizontal motion does not necessarily indicate the danger of the earthquake and the distortion of the new activity on the fault has changed.
