| 中文摘要:断裂带内的断层泥是断层新活动的产物，它记录了断层新活动的多种信息。依据分形理论对仙女山断裂带内断层泥粒度分维值与断裂活动关系的研究结果表明仙女山断丢以粘滑为主，兼有蠕滑。结合其它研究成果，对仙女山断裂活动及其对水电工程的影响进行了评价。 |

| Fractal Dimensions of Fault Gouges from the Xiannüshan Fault and Its Activity |

| Abstract:Fault gouges in active fault zones record a lot of impo rtant information about recent fault activity. In this paper, the authors try to discuss the relation between the fractal dimensions of fault gouges from the X iannüshan fault zone and its activity based on the fractal theory. The results s uggest that the fault is characterized essentially by sticky slip, with some ste ady creeping slip. Based on the above coupled with other results, the fault act ivity and influence on hydroelectric projects are also discussed. |
