| 摘 要： | 利用跨鲜水河断裂带的两个激光测距小网 1985～ 1997年的重复观测资料 ,分析研究了鲜水河断裂带的活动特征。通过对观测资料的数据处理 ,获得了测区较客观的位移场和应变场。形变分析结果表明 ,鲜水河断裂带北段处于蠕动状态 ,南段则处于应变积累的闭锁状态。

| Abstract: | By using the repeated observed data of two small laser range measurement networks across Xianshuihe fault zone from 1985 to 1977,the activity characters of Xianshuihe fault zone are studied.The displacement field and stress field of surveying areas are obtained through processing the observed data.The results of deformation analysis show that the north of Xiansuihe fault zone is in creep and that the south of the fault zone is in locking with strain accumulation. |

| Keywords: | Xianshuihe fault zone fault creep strain accumulation |
