| 摘 要： | 通过二维有限元对滇西北虎跳峡地区区域构造稳定性进行了系统研究。研究结果表明在现今区域应力场作用下区内不同方向的断裂活动性差异较大：北西向中旬-永胜断裂活动性最强，北东向丽江-小金河断裂次之，近南北向断裂如楚波-白汉场断裂最弱。

| Abstract: | Based on finite element analysis, the authors studied the regional stability of the Hutiaoxia (region) systematically. The result shows that the activities of the fractures change from place to place under the current regional stress-field. The activity of NW strike Zhongdian-Yongsheng fracture is most active and the safety degree is lowest, that of NE strike Lijiang-Xiaojinhe fracture is modest, and that of nearly SN fracture such as Chubo-Baihanchang fracture is weak and its safety degree is highest. |
