| 摘 要： | 鹤庆—洱源断裂位于滇西北,呈NE-SW向延伸,南端与红河断裂带斜交,是一条晚第四纪以来仍在活动的断裂。通过对鹤庆—洱源断裂的野外露头的特征分析,揭示了该断裂在晚第四纪以来具有左旋走滑特征,同时又伴有张性正断性质,结合该断裂带附近的地震活动特征分析,认为该断裂对滇中引水香炉山隧洞工程有重要影响,应引起重视。

| Abstract: | Heqing-Eryuan Fault(HEF)is located in northwest Yunnan province and extends NE-SW direction.HEF has been active since late Quaternary,its southern tip is oblique crossing on red river fault.Detailed field work on HEF show sinistral strike-slip with tensional normal fault since late Quaternary,combined with seismic activity characteristics near by the fault,it is considered that HEF has important impact on water diversion project Xianglushan tunnel project in central Yunan and should be brought to the forefront. |
