| 摘 要： | 根据野外调查获得的第一手资料,结合前人有关雾渡河断裂的研究成果,论述了雾渡河断裂的区域地质背景、构造应力场、深部构造特征、地貌水系样式,其中重点解决了雾渡河断裂的运动学特征和断裂活动时代.根据所采断裂上覆第四纪沉积物样品的TL测年数据(76.43±6.49 ka),确定雾渡河断裂晚更新世以来活动不明显. |
| 关 键 词： | 三峡地区 雾渡河断裂 断裂活动性 地震危险性评估 地质灾害预防 |

| Abstract: | On the basis of field investigation data along with related previous works we discussed the geological background,regional stress field,deep structural features,geomorphology and riversforms.Besides,the Wuduhe fault kinematics and fault activity were highly focused.TL dating data(76.43 ± 6.49) ka from the overlying Quaternary sediment samples confirm that the activity of Wuduhe fault zone fault is not obvious since late Pleistocene,which will provide some reference value to the Wuduhe fault zone seismic risk assessment and prevention of geological disasters in Three Gorges reservoir area. |
| Keywords: | Three Gorges area Wuduhe fault zone fault activity seismic risk assessment prevention of geological disasters |
