摘　　要：塔尔湾—登登山—池家刺窝断裂是阿尔金断裂东端发育的多条北西向断裂中规模最大的一条,对于该断裂前人在活动时代、活动速率、古地震期次等方面做了大量工作,但对于该断裂的分段特征及最大潜在地震的分析较少。本文在前人研究成果的基础上,根据活动断层分段的原则对该断裂进行了分段,并根据经验公式,评估了断层各段落的最大潜在地震。There are many NW-trending faults in the eastern segment of the Arguin fault.Their new activity characteristics are of great significance to the analysis of the neotectonic evolution of the east end of the Arguin fault.The Tarwan-Dengdengshan-Chijiaciwo fault is one of the largest faults of them.A lot of works have been done on the active age,active rate and paleoearthquake period of the fault.However,the studies of segmentation characteristics and the analysis of the maximum potential earthquake on the fault are few.In this paper,based on previous research results,we put forward the segmentation and the maximum potential earthquake of the fault according to the fault segmentation principle.
