| 摘 要： | 本文分析了老虎山断裂的基本特征，在此基础上运用活断层的自然分段、几何学特征分段、运动学分段及破裂分段等分段原则，对老虎山断裂带进行了分段研究，其中着重研究了破裂分段问题。老虎山断裂带可以分成４段，从东到西依次为喜集水段、老虎山段、草峡段和黑马圈河段。对断裂分段的研究可以为地震的中长期预报提供重要依据。

| Abstract: | Based on analysis of the basic features of Laohushan fault zone,this paper discusses thesegmentation of the active fault zone by using the natural,geometric,kinematic and rupturefeatures of active faults as the segmentation principles.It emphasizes the rupture segmentation.The results show that Laohushan fault zone can be divided into 4 segments:Xijishui,Lao- hushan,Caoxia and Heimajuanhe segments. The segmentation can provide important informa-tion for mid-long term earthquake prediction. |
