本文通过野外地震地质考察和系统的年代学样品的采集与测试，对华蓥山断裂带的第四纪活动性进行了讨论，并分析了该断裂带可能存在的分段特征。在对川东地区为数不多的中强地震震例分析的基础上，探讨了川东地区中强地震（Ｍｓ＝４７－５７）的发震构造条件。以此为依据，确定了华蓥山断裂带中段的最大可能潜在地震能力。
This paper discusses the quaternary activities of the Huaying Mountain fault zone through the field seismic geologic investigation and systematic geochronological sample collection and testing, and analyzes the possible segmentation features of the fault zone. Based on the analysis of a few earthquakes in the eastern part of Sichuan Province, the seismogenic conditions of the moderate-strong earthquakes in eastern Sichuan Province (Ms = 47-57) are discussed. Based on this, the maximum potential seismic capacity in the middle section of Huayingshan fault zone was determined.
